I read about this idea for mini lap books on a website where they call them "tot books" because they are designed for toddlers. My first one is extremely simple because I was really just trying to let the boys feel like they could participate while the girls were making the dinosaur lap book.
The idea is to cut a file folder in half and make all the projects inside teach simple basic pre-K skills like color and shape recognition, counting to 10, etc. I used my Sizzix die cut machine to make the dinosaurs and Danya put dots on them so the boys could practice counting the dots up to ten. I like these and hope to make more and better ones in the future.
