This is a Project Based Learning activity. It is great if you are in a K-8 school or have an elementary school near by. The goal is to create children's books based off what students learn about Westward expansion and simplify the content for younger students. Just be careful to make sure student's don't get too wrapped up in the decorating!
For any IB teachers I used this is a criterion A, C, and D summative for the unit. The goal was to get students to embed vocabulary into the content. Here is an example of a book I made in a college technology class that I used as an example.
