So simple in design … so easy to use … they must be magic!
The simple format allows young children to work without adult supervision while they learn, memorise and self check the addition and subtraction facts for numbers 1-10.
-
Addition: The sum of the two bottom numbers equals the number at the top of the
triangle
-
Subtraction: Start with the number at the top, choose a number at the bottom to subtract, cover the selected number and the answer will be the remaining bottom number.
There are exercises on the reverse of each card, by using a dry erase pen the combinations can be practised repeatedly. Great educational tool for any Youngstar!!
