  • Number: Multiplication and division

Pupils have used the word factor in describing multiplication equations and in this unit they deepen their understanding and use the word to describe factors and explore factorization of numbers. They will link this to their understanding of arrays and also explore the special cases of square and prime numbers and how this relates to their factors. This knowledge and understanding of factors will be applied when they use factorization to solve calculations efficiently.

  1. Explain what a factor is and use arrays and multiplication and division facts to find them
  2. Explain how to find all the factors of a number systematically
  3. Use a complete list of factors to explain when a number is a square number
  4. Explain how to identify a prime number or a composite number
  5. Explain how to identify a prime factor of a number
