Book Creator has long been a stellar app/webtool and recently I discovered that they have Templates to "remix." You can add templates to your app and do a collaborative work on your iPad among students, or if in a Chromebook environment your free account will allow you to share with students' Google accounts easily. This is an attractive option because, well, they are attractive and you don't have to design the Book yourself. Richard Byrne describes the magic ink and autodraw features here.

These "activity books" are filled with language underpinnings like storytelling opportunities, semantic knowledge and vocabulary. You can easily copy and modify any page to cater to your students before starting the activity. For example, on this page below, you can zoom in on a map and have kids in the group find out where others live (generally) for spatial/academic/biographical knowledge of others. Additionally, with this template, gratitude is literally good for your brain to practice all year long.
