In this worksheet, children apply the strategies they have learned so far to solve addition and subtraction problems with more than one step.
Children choose the operations needed at each step and then perform the calculations using an appropriate mental or written method.
Problems are presented in word form.
The use of bar models can help children to illustrate problems of this kind. While the models will not perform the calculation, they will help children to decide what operations are needed and why.
Ask,
What is the key information in the question?
What can you work out straight away? How does this help you to answer the question?
How can you represent this problem using a bar model?
Which bar will be longer? Why?
Do you need to add or subtract the numbers at this stage?
How do you know?
