This product is perfect for first graders learning how to count to 120! This allows students to practice, before and after, and ten more, ten less! This product includes, two types of "recording sheets" so you can differentiate. Some of my babies weren't ready for ten more ten less so they just stuck with before and after counting. This product also includes monster number cards 1-120. For my struggling babies, I allow them to use the monster cards as a puzzle, and put them in order.
