Prime Numbers Video Tutorial

Teacher Specific Information

During this Prime Numbers Video Tutorial, Martin tells pupils what a prime number is and then demonstrates how to tell if a number is prime or composite. Pupils have the opportunity to identify prime numbers before moving on to working out the prime factors of different composite numbers. The method shown by Martin involves using factor trees and the children have the chance to apply what they have learned in the last question. Martin uses terminology such as prime numbers, composite numbers, prime factors, factors and factor trees.

This video will be useful for children to watch at home or for extra support as part of an intervention, or whole class activity.
