AddTwo, created and tested by math educators, gives children an early understanding of adding with single digit numbers. Kids can work independently, or with a parent, learning how to make a visual connection with addition concepts. 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, AddTwo gives kids an edge.
