This resource was made for my Year 7 group. It was the first of a set of lessons on factors, multiples and primes, and was designed to teach them some key tests to help decide if a number was prime.
I printed the slide with the key divisibility tests on, and the pupils used whiteboards for slides 7 through 10. I also printed the grid of questions for them to work through on Slide 11.
The challenge questions at the end were used to stretch my more able and are based on those from the Junior Maths Challenge.
