AddThree

Created and tested by math educators, AddThree helps students learn how to add three digit numbers. Kids can work independently, or with a parent, learning how to make a visual connection with the idea of “crossing ten” and “regrouping". It’s a powerful tool for teachers and parents to engage children and make learning a process they can enjoy together. Amazingly direct and effective, AddThree gives kids an edge. *Pre-Requisite to the OverTen app.
