Addition and Subtraction Practice

This page opens Easy Math mode: addition and subtraction with numbers up to 20, never with a negative answer. It's designed for children building fluency with number facts – the foundation for all later mental math.

Rounds last 60 seconds, so practice is short and focused. A big on-screen keypad makes it easy to use on a tablet.

Number facts to work on

Number bonds to 10 (7 + 3, 6 + 4…).
Doubles (6 + 6, 8 + 8) and near doubles (6 + 7).
Bridging through 10 (8 + 5 = 8 + 2 + 3).
Subtraction as finding the difference.
Fact families: 9 + 4 = 13 means 13 − 4 = 9.

Tips for parents and teachers

Keep sessions short – one or two rounds a day is plenty. Celebrate improvement rather than the raw score, and encourage counting on from the bigger number instead of counting from one.
