Details

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.

Use a whiteboard marker to complete the revision exercise on the back of each laminated card.

Contains 35 cards measuring 13.5cm x 13.5cm.

Addition

The sum of the two bottom numbers equals the number at the top of the triangle. 7 + 3 = 10 3 + 7 =10

Subtraction

Start with the number at the top. Choose a number at the bottom to subtract. Cover the selected number. The answer will be the remaining bottom number. 10 - 7 = 3 10 - 3 = 7
