This activity is about finding three more facts from a given subtraction fact.

 

Example

We know that 260 - 136 = 124.

Which other facts can we get from this?

 

Answer

There are two addition facts and one subtraction fact that we can find from this.

 

Addition

The two smaller numbers add to make the largest.

124 + 136 = 260

136 + 124 = 260

 

Subtraction

260 - 124 = 136

 

If you get confused, think of an easier example such as:

8 - 2 = 6

 

From this we can get

8 - 6 = 2

and

2 + 6 = 8

6 + 2 = 8

 

Does that help?
