Securing understanding of factors, multiples, squares and cubes

I can use the multiplication tables to identify factors and multiples.

Lesson details

Key learning points

  1. Multiplication tables can be used to find multiples of a number.
  2. Multiplication tables can be used to find factor pairs of a number.
  3. Multiplication tables can be used to identify multiples of a number.
  4. Multiplication tables can be used to identify factors of a number.

Common misconception

All factors of all integers will appear in a 12 by 12 times table grid.

It is not possible to identify all factors of 24 using a 12 by 12 times table grid.

Keywords

  • Multiple - A multiple is the product of a number and an integer.

  • Numerical factor - A numerical factor is a factor that is an integer.

Get students to find all the factors of 100 from a 12 by 12 grid. They will not be able to find the factor pair 1 and 100. The multiplication grid needs to be big enough to find all of the factors of an integer.
