# TES Maths ROTW: Factors and multiples game

Consolidate secondary students' understanding of factors and multiples with this engaging game, as recommended by TES Maths

## TES Maths Resource of the Week

### What is it?

This engaging game is a take on a classic activity that has been used in maths classrooms for years, but with one unique difference. My "ultimate edition" includes ideas for extensions, variations and lines of enquiry from the students and teachers I've met on my travels around the country. It is this extensive input that makes this game ideal for a range of classes during the first few lessons of the year.

### How can it be used?

We use this resource with our new Year 7 classes in the second week of term. Although they will have studied factors and multiples from Year 4, it is a concept that needs to be reinforced. Not only does this game do that in a stimulating way, but it also sets the tone for the study of maths in secondary school, painting it as both a fun and challenging subject.

All students start by playing the basic version, before it gets differentiated through different lines of enquiry. These are listed in the review section underneath the resource, but some of my favourites are:

• If you start with 20, how many different numbers can you choose?
• Do bigger or smaller numbers give you more choices? Explain your answer.
• What is the lowest number you can choose and still win?
• How long can you go if you avoid the prime numbers?
