Archaeologist Jones and the Mystery of the Missing Digit Maths
This worksheet is designed as a pretest to see where your students are at in their ability to use inverse operation with addition and subtraction.
It is a part of a larger unit where students learn a variety of pre-algebra 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.
