Here is a Agamograph style project for Halloween. Your students can choose three pictures and make them into one, by flipping them from the left or to the right! There is even a blank template for your students to draw their own picture or pictures. You can even have them mix and match with one of their own and two pictures that have been drawn. Another idea is to place three students in a group to create one blind. You also could have your students write a scary story or a Halloween they remember and glue it near your picture.
