Worksheet Overview

In this activity, we will find the missing number in a given calculation.

 

Example

Work out the missing number:

 

1000 - _____ = 219

 

Answer

We can use the fact that 1000 - 219 will give us our missing number.

 

1000 - 219 = 781

 

1000 -   781   = 219

 

We will need to think about doing the inverse of calculations to solve many of these questions.
