About Number Ninja
Number Ninja is a free math game for kids that makes practicing sums quick and fun. A sum appears at the top of the screen, and you tap the right answer from three big buttons before the timer bar runs out.
How to play
- Read the sum, like 3 + 4 = ?
- Tap the right answer. On a keyboard you can also press 1, 2 or 3.
- Need help? Count the little fruit pictures under the sum.
- You have 3 lives. A wrong answer or running out of time costs one, and the game shows you the right answer.
Gets harder as you learn
The first sums only go up to 8, perfect for children just starting to add. After a few correct answers the numbers get bigger, and later subtraction sums join in. The timer gets a little shorter too, so kids build speed as well as accuracy.
A great way to practice mental math at home or school. Free, no sign-up, no download.
