Eric Carle’s The Mixed-Up Chameleon is a nice book to explore different mediums with. Here are some ideas:
Here’s a Mixed Up Chameleon Lizard you can photocopy for each child.
If you’re working with younger children, you can use this Mixed Up Chameleon Parts as a guide for the different animal parts. If the children are old enough, have them cut out the pieces free hand. You can use tissue paper you’ve already decorated (see the Eric Carle Club).
If you have enough prep time, you can make rubbing plates of the different animal parts and have the children use crayons on tissue paper to create the shapes. You just need cardboard squares and white glue.
