I used this to help my students count by 10s. Each piece of the caterpillar has a dime on it. I printed the pieces out on colored paper and the students cut out as many dimes as they wanted. After creating a caterpillar, students had to count the money amount and write it on the head of the caterpillar. To help some students, I had them also write the amount under the dime to show their counting. They came out great!
