Counting On

 

To count on, I always take the larger number in my sum and add the second number. 

 

I can add on by counting up in my head and/or using my fingers. 

 

For example, if the calculation is 13+4. I start with the number 13 in my head, put up four fingers and count 

1 - 14

2- 15

3 - 16

4 - 17

 

Then I know the answer is 17. 

 

Have a go at these calculations below:

 

6+7=

14+5=

10+8=

3+9=

6+9=
