Combine division with addition and subtraction

Order of operations

Unit Summary

In this unit pupils will explore what happens when we combine addition and subtraction with multiplication and division, bringing up the need for the order of operations.

Lesson Summary

You will learn to explain which order to complete the division and addition or subtraction elements of a problem, and you know how to write this as an equation.

Key Notes

  • Division can be combined with addition and subtraction.
  • When there are no brackets, the division is completed first.
  • Where there are brackets, the calculation within the brackets is completed first.

Vocabulary To Learn

  • Brackets: Brackets are symbols used in pairs to group things together.
  • Order of operations: The order of operations is a set of rules that tell you which operations have priority over others in an equation.

Common Mistakes To Avoid

  • Children may struggle to identify the dividends and confuse these with the divisor.

3 Quick Questions (With Answers)

Mistake: Children may struggle to identify the dividends and confuse these with the divisor. Correction: For each problem, ask the children what each number represents and help them to describe this. For example, 'the number of sweets before they were shared and the number they are sharing between' alongside the terms dividend and divisor.
