Proof review sheet

A KS4, or upper KS3 maths topic review sheet on proof. Questions are shown alongside fully worked answers and tips to help guide understanding. The sheet is divided into sections, covering:

• counter examples of statements such as all prime numbers are odd;
• algebraic proof of statements such as the sum of three consecutive numbers will be a multiple of 3.

Students could be given the questions initially and then the answers to mark and correct their work.
