Why this why now
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.
Prior knowledge requirements
- Know multiplication facts to 12x12
- Identify square numbers
- Recognise and list factors of a number
