Practise Your Subtraction (3)

In this worksheet we have to work out a subtraction by counting on using a number line.

Example

Work out 332 - 153 =  __

We use the number line to count up from the smaller number to the larger number.  

First step: go to the next hundred, i.e. 200 here

Second step: count up in hundreds to the hundred below your given number, i.e. 300 here

Third step: count up to the given number, i.e. 332 here

Answer is 47 + 100 + 32 = 179
