How the ES library supports reading and writing at CAC

The CAC elementary school does a fantastic job of teaching reading and writing using a workshop model. Teachers guide students in acquiring literacy skills and strategies, and students have lots of opportunities to develop those skills.

The ES library supports the literacy workshop model in many ways. Here are a few of those ways.

The Library Catalog's Visual Tab

I use our Destiny catalog's Visual Tab as the central access point for library print and digital resources.

The Visual Tab is visible from all the pages of the library catalog. Students learn to go to the Visual Tab from grade 1. 

Each grade level has a page on the Visual Tab. 

Take your time to visit the library catalog and explore all of the different pages. Literature integration such as book lists or specific websites are in the "CAC Units of Study" page, which is broken down by grade level. In each grade level, there are links to the all the science and social studies units, and for some grades, links to literature integration resources. 

On this grade 4 page, there are links to the 6 science and social studies units, and links to language arts and literature integration resources.

Each unit page includes at least one book list and has many links to teacher-selected webpages.  

Library lessons for preK to grade 2

All ES classes are scheduled for a weekly checkout session. For preK to grade 2 classes, that includes a library lesson. Usually, those library lessons include a read-aloud and basic library skills, like how to use shelf markers to return books to shelves in the picture book section and how to care for books. We try to tie the read-alouds to topics that are being studied at each grade level or that illustrate the CAC core values. 

In second grade, as students become more proficient readers, we start introducing more advanced library skills, like using the call number to locate books on shelves and using the catalog for research. For example, grade 2 right now is embarked in a informational reading unit so I gave them an overview of how our non-fiction collection is organized by Dewey Decimal system and how to browse the shelves noticing the titles and call number stickers on the spine. 

Genre stickers, displays and book talks

Our fiction collection is organized alphabetically by author's last name. To help students locate books in different genres, we have label stickers that we place on the spine. We also place small selections of books in each genre on top of the chapter book shelves, with an accompanying poster. When students are engaged in genre studies, I give them a brief talk about how to find titles in those specific genres and we often designate our display table at the front of the library to selections that will support grade level units of reading or writing. I also give book talks where I promote the best examples of each genre at the request of the teacher. 

Research skills

Grades 3 to 5 come to the library for a scheduled weekly checkout. Instruction in research skills happens at different times as needed by the requirements of each unit. I go to classrooms to help introduce and review those skills. We have an information literacy skills continuum that helps guide the progression of skills to ensure that we are preparing our students for middle school and beyond. We use the Big Six research model at CAC, and I am usually working with students on Steps 2 and 3: "develop research strategies," and "locate and access information."

Starting in second grade, I encourage students to use online databases for class and homework. The databases that we subscribe to on behalf of CAC are listed on the Home Tab of the library catalog. To access that page, you will need to log in to the library catalog using your CAC single-sign-on or our Quick Login. If you are a CAC parent of a student in grades 2 to 5, you should be able to ask your child/ren to help you. We practice accessing the library catalog a lot!

Collaboration with teachers

Last, but not least, I try to collaborate with teachers as much as possible to integrate information literacy skills to their classroom programs. We have an incredibly talented and dedicated team of teachers in the ES. The work they are doing in the reading and writing workshop is really inspiring and the results from the students are impressive.  It is a privilege to work with them.

Where to find images for school

Need images for a school project? The best option would be to take your own pictures or create your own images to use for a school project, but when that isn't practical, here are some alternatives.

Not all images are free for use, and even if they are, digital citizenship requires you ask for permission before using. Instead of using Google Images to find a picture, head over to the ES library catalog for ethical alternatives so that you can demonstrate the CAC core values of integrity and respect.

Students in grades 2 and up will be learning how to find images for for which they have permission to use and how to cite the sources of those images. 

Here are a few places to start your search for images. 

Britannica Image Quest

This subscription database offers millions of high quality available for students to include in their work. Britannica Image Quest offers images from many reputable sources, including government archives, famous museums and stock photography collections.

Britannica Image Quest is a subscription database, which means that we pay a fee on behalf of our CAC community, and that log in credentials are required. Students in grades 2 to 5 receive a card from the library through their classrooms with all usernames and passwords for all of our databases, but CAC patrons can also use the Quick Login. (All ES students know the Quick Login. Ask your child or stop by the ES library to request it.)

Wikimedia Commons

This site from the Wikipedia family offers 36 million images uploaded by users. Each image is available for download in different sizes and permission details are included on the page. There's even a monthly challenge for photographers.

The search interface is not as elementary school friendly as some other sites, but it is a good option for our older students.

Creative Commons Search

Creative Commons licenses are  sets of permissions for work of all types. By invoking a Creative Commons license, creators of content let people know what type of credit they would like for their work. Here is a very easy explanation of the main four types of licenses. I've also link to this explanatory cartoon on the Visual Tab.

The Creative Commons Search link on the Visual Tab will take you a site where you can search for different types of media: images, videos, and sound files.

Photos for Class

My new favorite, Photos for Class,  offers copyright friendly images that include the proper attribution right on the image once you download it.

Grade 3 sound and light links on the Visual Tab

The grade 3 is currently studying a science unit on light and sound. As with other units, the library catalog has a page with links to support students in their inquiries.

How to access this Visual Tab page (for a step by step tutorial with images)

• Visit the library catalog and choose the elementary school library
• Look for the tab marked Visual. (It's above and to the right of the search field.)
• Click on the button with Talon. It's called "CAC Units of Study."
• Click on the grade level and then the unit. 

Each of the buttons on the page will take students to sources selected by the classroom teachers or the elementary librarian. I look for sources that are authoritative, accurate and reliable, and as current as possible. I welcome suggestions from the classroom teachers and from students. I give priority to informational sites over educational games sites. If you know of a good source for information on light and sound - or any other science topics - please let me know in the comments.

Note that Britannica Encyclopedia and BrainPop are subscription databases and require username and password. Students in grades 3 to 5 have been taught to access our passworded list of login credentials. The lower grade levels have printed out cards with the logins for the most used databases.

If you are a parent at CAC and missed our parent information session where we demonstrated how to access the library catalog's resources, please stop by the library for help from Mrs. Fitzgerald.

Grade 4 Social Studies on the Visual Tab

Grade 4 is currently studying a social studies unit called, Connections to History. The essential question for this unit is,

How do geography and people connect to build a nation?

Our fourth graders will focus this question by looking at Native Americans and specifically their settlements, use of resources like food, shelter and clothing, and cultural traditions. One of the projects that will track their learning throughout the unit is going to be a multi-layered map that will show Native American nations geographical regions and movement. We started that map today. 

Students came to the library to start on the map project and also to review the steps of the Big 6 research model. The Big 6 is an useful model to use when embarking on an academic task. More information on it can be found here.

The map that we created today is a physical map. It shows the landform regions of the US. Students accessed the Visual Tab to see the map they would be duplicating on paper. 

(To access the Visual Tab, visit the library catalog, then click on the tab marked "Visual." From there, click on CAC Units of Study, and then follow the picture clues to the grade level and unit you need. There are resources for most social studies and science units in grades 2 to 5, as well as links to poetry websites, mathematics websites including Mathletics, online newspapers for children, and much more. Go ahead and explore. If you would like a guided tour, please contact me at the library.)

The Visual Tab page for the grade 4 Connections to History unit looks like this. The map we reproduced today can be found by clicking the button "Map USA-Landforms."

The resources linked here include books from our library catalog, links to database articles from Britannica Online and TrueFlix, and websites. To access Britannica and TrueFlix, students will need to log in. Their teachers should have given them the log in credentials, but those can also be found by logging in to the ES library catalog. All g3 to g5 students have been taught how to do that. If they cannot remember, please contact the ES librarian, Mrs. Fitzgerald. 

Recommended Book Lists on the Visual Tab

The Visual Tab of our library catalog is where we gather all sorts of resources for the CAC community. One of these resources is our selection of book lists.

CAC was fortunate to have a visit last week from literacy consultant, Christy Curran. Her presentation to parents on how to encourage children to read was well attended and filled with excellent advice.

One of the tip that most resonated with me was about "reading to your children, with your children and reading along with your children." My children are teenagers now, but we spent a lot of time reading together when they were little. I wish we hadn't stopped! Our reading time was special.

One happy benefit of our early reading life is that my 17-year-old son has started recommending great books to me. So far I've read The Martian, Wool and Ready Player One thanks to him. I've loved them all, but what I've loved even more are the discussions we've had about the books.

Receiving recommendations from others is a great way to discover new authors and genres. The library catalog has collected several lists recommending books on its Visual Tab. Click here to go directly to the Visual Tab Book Lists page.  Continue reading below for instructions in how to get there.

To access the library catalog's Visual Tab,

1. navigate to the library catalog. (We recommend bookmarking it on your browser.) http://cacegypt.org
2. Select the elementary library catalog. 
3. Click on the tab marked Visual on the main search page.
4. Click on the "Book Lists" button. 

You will see links from the American Library Association as well as lists of US and UK award winners. All of these include quality literature for children. We have most of the titles featured on those lists. 

Also on the Book List page are two websites: Common Sense Media and the Scholastic Parents' page. These offer recommendations by age. The Common Sense Media website includes reviews on books, movies, apps and other media. One thing that I like about the Common Sense Media site is that for each of the books (or movies, apps, etc.) it includes a section called "Families Can Talk About..." which lists discussion points for the book. 

The Scholastic Parents' site includes recommended lists by age here, and lots of resources to help with homework. 

Please note that including these two sites in this blog post does not constitute CAC endorsement for either. They are offered only as an additional resource. 

Online Summer Reading

The end of the year at a school is usually super busy. The ES library has been a hive of activity as well, and it's just kicking up into high gear as we race to collect all the library materials in time for the last day of school. Our school policy is to withhold report cards for students with overdue materials, and I always try my hardest to make sure that no child gets blocked. So far, in my eight years as a librarian, I haven't been able to accomplish that, but...there's still this year!

One of the things we do during the last weeks of school is promote our online reading materials. While students are allowed, and encouraged, to check out books for summer reading, we also know that in this day of ubiquitous Internet, online options are welcome, especially for our expat community. Summer means long travel times and ebooks pack light.

Here are a few options for online children's reading.

Online reading on the Visual Tab

The Visual Tab houses a treasure house of learning resources during the school year, and is available year round to students wherever there is an Internet connection. We have a page of online reading for children with links to our Overdrive collection (more on that later) and reading websites. 

The Current Events for Kids page has a collection of online news sites for children, from different countries and in different languages. As of the time of typing, I don't have a website for children in Arabic. If you know of one, please do let me know in the comments.

The Children's Online Books page has links to several websites offering online children's books, including our Overdrive collection.

The International Children's Digital Library has books in many different languages. Many of the books can be read for free. A free account allows users to upload books of their own.

Starfall is a literacy website for younger students. Many of our second and third graders welcomed it as a long lost friend, and spent a lot of the time in the lesson playing its educational games.

Storyline Online is sponsored by the Screen Actors Guild and the Entertainment Industry Foundation. It features famous US TV actors reading favorite picture books. This is a great mentor site for reading with expression.

Myths and Legends is a site that offers myths, legends and folktales from different countries. Most of the countries are Anglo-Saxon, with a sprinkling of stories from other cultures. The site also allows users to submit their own stories.

Lit2Go is a collection of stories, novels and poetry in mp3 format. It is sponsored by the University of South Florida. Download the mp3 and play through iTunes or an mp3 player app.

StoryNory offers stories in podcast episodes. Each episode can be downloaded individually or subscribed to through a podcast app.

YASync is a site that offers 2 free downloadable audiobooks per week of the summer. These are suitable for older students.

Overdrive eBook Collection

CAC has a large collection of ebooks available through Overdrive. Books can be read online or downloaded to a mobile device app. Instructions for using Overdrive can be found here. 

Although CAC has two separate collections for the elementary school and the middle-high schools, we cannot separate our ebooks separately, so parents are urged to supervise their elementary school students' ebook choices. 

To access the CAC Overdrive collection, patrons must log in with their single sign on username and password. 

A link to Overdrive is available via the Visual Tab's Children's Online Books, or by logging in to the library catalog. 

TumbleBooks

TumbleBooks is another collection of ebooks, featuring animated picture books, ebooks with a read aloud function, graphic novels, audiobooks, non-fiction videos and more. We actually have 2 different collections: the original TumbleBooks, for students up to grade 3 and TumbleBookCloud Junior, for students in grades 3 and above. However, after trying both out this week with grades 3 to 5, we all think that the original TumbleBooks has the better selection of ebooks. 

To access TumbleBooks, you will need to log in to the library catalog using the Quick Login or your single sign on. Scroll all the way down on the homepage and note the username and password for TumbleBooks.

Scholastic BookFlix and TrueFlix

BookFlix and TrueFlix are 2 other ebook collections. 

BookFlix was the original database. It pairs an animated video of a popular and/or award winning book with an ebook. It offers comprehension games, short author bios, and links to related websites. 

TrueFlix is for older students and links to social studies curriculum. It pairs a short documentary with an ebook. 

To access these, log in with the Quick Login or your single sign on to the library catalog, and scroll down to their links. Note the username and password listed for each. 

And there's more!

If you or your child is more interested in non-fiction material, explore the databases we provide. Find links and login credentials on the library catalog's homepage. (Access the homepage by logging in with the Quick Login or your CAC single sign on.)

Questions? Stop by the ES library for a demonstration.

ES Library and Grade 5 Journalists Making Headlines!

The grade 5 unit recently embarked on a journalism unit in their literacy workshop. The ES library is very happy to support them in this unit, as we have many resources to help them in their journalistic endeavors.

All 3 classes came to the library for a session on journalism sources and how to access many from the library catalog.

Journalists must keep track of their sources. We ask our grade 5 journalists to maintain a bibliography of citations. Templates for the citations (in MLA format) can be found in their student planners or on the Visual Tab grade 5 page. Citing our sources is one of the ways we demonstrate our CAC core value of integrity.

1. Personal interviews and observations
• Journalists find stories in the world around them. Our grade 5 students are encouraged to do so as well. 
2. Written materials, e.g., primary sources and  magazines
• Primary sources would include letters, maps, recordings and other materials created at the time of the event being 
• Magazines and other periodicals - we have many childrens' magazines in the ES library. They are getting checked out frequently for this unit. We remind the students that magazines and other periodicals are often printed on flimsy, inexpensive paper and so they must take extra special care with them. 
3. EBSCO's Primary Search database -- link on the library catalog's Visual Tab Current Events  page and the Home page.

• 
  
• This is one of our subscription databases. It searches for keywords in children's magazines. 
• Students are encouraged to use subscription databases because they are reliable sources of information. 
• Primary Search database allows students to filter results by time, subject, publication, geography and other limiters
• It also provides a citation for the article in question. This citation can be copied directly onto a bibliography
• 
  



4. WebPath Express -- on the library catalog
   
• WebPath Express is the search engine for our Destiny catalog. It searches for keywords in a large collection of websites vetted by teachers and librarians. While it may not return the most current of articles, it does return relatively authoritative and reliable sources. 
• To create a citation for an article found through WebPath Express, students will need follow the formats given in their student planners or on the grade 5 Visual Tab for research skills. 
5. Kiddle.co -- link on the library catalog's Visual Tab Current Events page
   
• Kiddle.co is a search engine for kids. It uses a customized Google search to first find articles written for children, then articles written for adults but accessible to children and finally articles written for adults. 
• The News tab on the Kiddle.co site will look for articles in children's online news sites first. 
• To create a citation for an article found through WebPath Express, students will need follow the formats given in their student planners or on the grade 5 Visual Tab for research skills. 
• When looking at websites through Kiddle.co, students should consider our website evaluation criteria, PAARC. (P-purpose, A-authority, A-accuracy, R-relevance, C-currency)
6. Current events page on the Visual Tab
   
• 
  
• The Visual Tab has a "Current Events for Kids" button. That will take you to a page full of links to online newspapers and magazines for children, from many countries and in different languages. Unfortunately, each site has to be search separately, but for the most part, these online news sites are quite current. Facts should always be cross checked. 
• We do not have an online site for children's news in Arabic, so if you know of one, please let us know so we can add it to the page. 
7. LAST resort: Google search
• Google search should be the last resort, to be used only if none of the other sources produce the information sought. 
• For our journalism purposes, we often are interested in different perspectives, so we can focus our search results by using the code, "site:", and adding the 2 letter country code. For example, a search for "Olympics 2016 news site:.eg" will give us results of news published in or about Egypt. 

Journalists must have at least 2 verifiable sources for the information they report on. This forces journalists to double check their facts. Our young journalists will be held accountable to the same standard. Using this list of sources will ensure that they know where to look for information.

Supporting Grade 5's Historical Fiction Unit

Grade 5 students are starting a historical fiction unit in their reading workshop. The essential questions for this unit are:

• How can I read in a way that lets me trace themes in these stories and think about the author’s craft?
• How does talking about books encourage and grow ideas?

To help answer the first question, I collected fiction and non-fiction resources from our print and digital collections on a libguide. Normally, I gather resources for students and post them on the Visual Tab of the library catalog, but this time around I thought that it might be a good unit to introduce our fifth graders to the libguides they'll be using in middle school. Also, libguides allow me to include more information about the different resources than the Visual Tab does. 

The grade 5 historical fiction libguide has tabs for different time periods, corresponding to historical periods reflected in the novel sets the grade 5 students will be reading. On each tab, there is a selection of non-fiction books and links to our databases for each period, and a selection of picture books set in that period. The grade 5 students will be using the non-fiction information to gain an understanding of the historical context for their book club novel. Along with the picture book selections, they will be looking for connecting themes. This is deep reading work, and I'm very pleased to be helping them become even more expert readers. 

Update 14 March, 2016: Just ended a class with one of the grade 5 classes and was delighted to hear students expressing how understanding the historical context of a novel will help them comprehend it better. That's why I love collaborating with teachers - it always leads to enhanced learning. 

Supporting Grade 5 with the catalog's Visual Tab

This year I've added lots of resources to the grade 5 Visual Tab of our library catalog. Many of the links have been suggested by the grade 5 teachers themselves, and the Visual Tab is getting to be a great resource for fifth graders.

This is a screenshot of the Visual Tab page for their upcoming unit on earth science.

These links give access to videos and text to support their unit. Many of them are requested by the grade 5 teachers. To be posted here, these sites comply with our PAARC guidelines for websites. PAARC stands for Purpose, Authority, Accuracy, Relevance and Currency. (These criteria are also sometimes known as CRAAP, but since I worked with elementary students, I prefer PAARC.) PAARC merits a blog post of its own. Stay tuned.

This is a screenshot of the research links page on the Visual Tab. This includes a list of books about research and links to a bibliography template and citation samples. I'll soon be adding the PAARC poster to the page.

Here's a screenshot of the Visual Tab for the recently completed unit on world development and culture. This unit was only a few weeks long, so it was important to the teachers that students were very focused in their research. Having links to recommended sites helps students avoid the "Google-y eyes syndrome" where the sheer number of Google results means that they spend more time scrolling down the results page than on deep reading of the material they find. 

We have Visual Tab pages for most of the ES social studies and science units of study at CAC. Pages for grades 3 and up are more fully stocked as we do a great deal of research support for those grades, but I do try to have some resources for all grades. 

Here's how to reach the Visual Tab. 

1. Visit the library catalog: http://library.cacegypt.org (Go ahead and bookmark this for quick access.)

2. Choose the elementary school collection. 

3. Click on the Visual Tab tab on the main search page. 

4. Navigate using the picture clues. The social studies and science links are on the CAC Units of Study page. 

This is the same regardless of what grade level you are interested in. Please do take a look at the resources on the Visual Tab and let us know if you or your children find them useful. 

Keep your New Year Resolutions with the ES Library!

Have you set yourself New Year resolutions? Let the CAC ES library help you keep them! (If you haven't set them yet, it's not too late!)

Scroll down the list to find inspiration for the resolutions you have already made for this year or for inspiration. -- One of my New Year Resolutions is to blog more so subscribe to this blog and cheer me on by commenting.

Eat more healthily as a family / Teach kids to cook

The ES library has a large collection of cookbooks suitable for children. The best way of ensuring that children eat everything on their plate is for them to be the cooks. Even little hands can help if adults handle sharp edges and heated surfaces. See here for a list of our cookbooks. You will notice that a lot of them are checked out, but if you log in with your CAC username and password, you can place holds on the books that are out. You will be notified via email when your titles arrive.

Cookbooks at the ES library - If this link does not work, simply visit the library catalog, choose the elementary library collection, and enter cookbooks in the search field.

Exercise more / Set up a family exercise routine

The 613 and 790 sections of the library have lots of titles on fitness and different sports. Come together as a family to the library to find exercise resources. We have an especially robust soccer section because we have so many soccer fans, and more are coming soon.

Stay in touch with current events / Help my children stay in touch with current events

The Visual Tab of the ES library catalog has a wealth of links to child-friendly news sites from all over the world. We are eager to have an even bigger resource, so if you know of good news sites for children in your language, please let us know in the comments or email me, jfitzgerald at g-cacegypt dot org.

Learn a new language 

The CAC ES library has a large collection of books in Arabic and languages other than English. If your New Year resolution is to improve your Arabic, be sure to stop by for recommendations from our library assistants who are well acquainted with our Arabic collection. That is housed in our beautiful Egyptian tent, so do come and enjoy the collection. 

Our "Multi-Language Collection" has books in more than 30 different languages. Most of these have come from generous donations of CAC families. If you would like to contribute by donating gently used books in your mother tongue, please see us. 

Read more fiction / Read more non-fiction

With over 25,000 titles, there's a book for everyone at the ES library. Here's some ideas to support your new/improved reading habit.

• Log your minutes for the Million Minutes of Reading Challenge. 
• Come to the library often. All you need is your CAC ID.
• Challenge yourself to read all of the Caldecott or Newbery Award winners.
• Set a number goal, e.g., 50 books this year.
• Find a buddy to discuss your book choices with.
• Start a book review blog, on your own or with a friend.
• Pick up an CAC bookmark at the library. It has useful links for you to get the most out of the library online resources.
• Download the Overdrive app on your mobile device and access our ebook collection. You'll need your CAC single-sign-on. 
• Ask us for reading recommendations. We love to talk about books!

Join a bookclub

The MHS library organizes a cookbook book club that is a lot of fun. Every month, we get together to sample dishes prepared from a selected cookbook. Meetings are usually on the last Wednesday of the month. Stop by the MHS library to browse through the book and sign up for a dish. 

Want a reading book club? At my previous school, we had a parent-library book club. Members met once a month to discuss a book chosen by consensus among the members. It was a great deal of fun and a highlight of my month. If you are interested in something like that, let me know. We could start one here!

Solar System Resources for Grade 2

Grade 2 is currently studying the solar system. Their essential questions for the unit are:

• How do we know about our place in space?
• What is our solar system and where do we fit in it?

The library has lots of resources, both print and digital, to help answer these questions. They are, as usual, gathered together on the library catalog's Visual Tab.

Print - We refreshed our astronomy print collection last year. The average year of publication for that particular section of the library was 1994. By weeding books that were older than 10 years, and purchasing lots of recent publications, we brought up that average to 2007. 

Grade 2 students learned how to browse the shelves, using the information on book spines to locate titles of interest. They also reviewed how to use the shelf markers to return books to the correct place. 

Click here for a list of solar system books that are good for grade 2 students. Most of the titles can be found in the 520s bookshelves in the non-fiction section of the library. The list itself is posted on the Visual Tab page for this unit.

Digital - We have many digital resources for grade 2, all accessible from the library catalog.

Visit the Visual Tab to see the collection of resources.

To get to the Visual Tab, visit the library catalog, http://library.cacegypt.org. Choose the elementary school library link, and click on the tab marked Visual above the main search field. 

PebbleGo is a particularly good resource. The content has been developed specifically for young researchers, and includes topics in science and social studies, including the solar system. The link from the Visual Tab takes you directly to the solar system section, but you'll have to first log in. Grade 2 students can refer to their catalog login credential cards in their take home folders. All other CAC patrons can log in to the library catalog using the Quick Login to see the full list of databases we subscribe to, as well as the usernames and passwords for each.

Another excellent resource is BrainPop and BrainPop Jr. BrainPop has engaging animated video clips featuring a robot called Toby. In BP Jr., a little girl called Annie accompanies him. One of the buttons on the Visual Tab, called "Space", is a shortcut to various movies about bodies of the solar system. The other button is a movie on gravity. Interested, and advanced students, could also go to BrainPop, the older version and do a search for solar system. Both BrainPop and BrainPop Jr. will require username and password. As above, refer to the login credential card or log in to the library catalog using the Quick Login.

Other sites on the Visual Tab page for the solar system include links to several NASA (the US space agency) sites and ESA (the European Union space agency.) Also useful should be the link to the National Geographic Kids videos. These do not require logging in.

Last, but not least, the Blendspace button has a collection of links to videos that the students have used in class.
