I LOVE this book. It was fun for the students to figure out the different ways to make a number. I put the book under the document camera and we solved the first few pages together and then each student got a paper with the picture on it. The students had circle them on their own, write the math sentence and then share their ideas. It's great practice without the worksheet but I wanted the students to create the math equations.
Here is the Picasso page. The students had to come up with six ways to make ten.
