About Three Numbers
Two signs and three numbers make one longer problem, like 2 + 1 + 3. Your child works it out one step at a time and taps the answer. The oldest kids get problems where times and division come before plus and minus, and parentheses go first.
How to play
- Work out the first step and remember the halfway answer.
