I just wanted to repost this tutorial because it is one of the simplest, easiest, most played with things I ever made for my daughter Olivia. I love how many ways she uses these foam shapes. I had only thought of them as being used to make art pieces in the bath/shower, but she sorts them by color, by shape, counts them, puts them on her arms, legs, and belly. The possibilities and educational opportunities are endless! See the old tutorial of mine here.
