Why kids like it
Every answer feels like completing a target, and the numbers grow only when the child is ready for a new challenge.
Start by making 10: find the missing amount that reaches the target. The first 20 questions build strong make-10 fluency, then the game grows through 20, 50, 100, 200, and 1,000 so children practise complements, mental math, and smart regrouping.

Can your child make 10 in every one of the first 20 questions?
