This foldable can be used when learning about different types of sentences. I originally just talked about it with my students but then I realized it didn't really sink in. So then with a front cover I found online, I added a definition and examples on the flaps that were relevant to class. Students can also write additional examples underneath the flaps when they glue it in their notebook. Goes along with Harcourt's 4th grade reading textbook StoryTown, grammar section in lesson 1 and 2.
