Worksheet Overview

QUESTION 1 of 10

In this worksheet, you must know your adding number bonds up to 20.

And that means knowing them off by heart.

 

Example

 4 + 8

 

Answer

12

 

Remember

4 + 8 is the same as 8 + 4.

10 + 6 = 16 and 10 + 7 = 17 and so on.

0 + 5 = 5 and 0 + 19 = 19 and so on.

7 + 7 is twice 7 so 7 + 7 = 14.
