Example

Find the missing number in the calculation:

 

134 + ___ + 22 = 160

 

Answer

Step 1:   Add together 134 + 22 = 156.

 

Step 2:   Work out what you need to reach 160 by calculating 160 - 156 = 4

 

So,

134 +  4  + 22 = 160

 

Does that make sense?

 

In this activity, we are going to be number detectives and find the missing number!
