I love interactive books. They are really great for minimally verbal students. They can show their knowledge without needing to verbally produce answers. For kids just learning to express themselves in single words or simple phrases, pictures support that level of speech and comprehension. If students are communicating in sentences they can make up their own language to describe the picture/scene.
Interactive books give little hands something to do. They also have a very clear ending. The kids can see if they get the pictures done they are finished with this activity. I can work on many additional goals (verbs, pronouns, functions, attributes, etc.) while targeting this activity. This meets the curriculum vocabulary for my preschool programs during the first month of school.
In this book you will get a story about the crazy things that are seen on Halloween. It brings general education books to lower functioning individuals that need the extra support. This is a great way to get the kids involved with their typically developing peers
