Multi-operation Missing Number Problems
In this worksheet, students will be required to add an extra step to their process, where they have to simplify one half of an equation before finding the inverse operation.
This worksheet is a part of a larger unit where students learn a variety of prealgebra skills, including equivalent equations and inverse operations, to solve multiplication and division problems with missing digits.

Learning goals
- We are learning to recognise and explain the connection between multiplication and division as inverse operations and use this to develop families of number facts.
- We are learning to find unknown quantities in number sentences involving multiplication and division, using the properties of numbers and operations.
- We are learning to find unknown quantities in number sentences involving multiplication and division and identify equivalent number sentences involving multiplication and division.
- We are learning to create and use algorithms using multiple steps to experiment with factors, multiples and divisibility and identify and describe emerging patterns.
