Something in Common 1: Think of a Number

Earliest recommended Year group: Year 8.

Simple game that finishes on 1, whatever your starting number. Leads to creating expressions and proof.

This is from the “Something in Common” collection of resources by John Burke. They allow consolidation of key skills, prevent students from copying each other (as all the questions are different), make marking and assessing easy for the teacher (as all the answers are the same!), and provide a lovely extra challenge for students as they try to figure out exactly what is going on!
