I just learned about CAST UDL Book Builder, which allows you (and your students) to create free and simple online “books.” Your completed books can even have little talking critters that prompt readers to use specific reading strategies when they’re reading. You need to register to use the site, but that can be done in a few seconds.
I heard about this online application from the Teaching Every Student blog. That blog entry has more specific information on the Book Builder.
I’ve placed the link on my Examples of Student Work page under the category Student Books. You can find it near the bottom.
