Checking understanding of factors, multiples, squares and cubes

I can state the factors and multiples for different numbers and identify square and cube numbers.

Lesson details

Key learning points

  1. Multiples of a given number are the product of that number and an integer.
  2. Factors of an integer can be identified by checking for a remainder when dividing.
  3. In the statement factor x factor = product, the product is a multiple of each of the factors.
  4. If a is a factor of b then b is a multiple of a

Common misconception

There is often confusion between factors and multiples.

Highlight that the number of dots in an array is the multiple and the number of dots in each column & row are the factors.

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.

  • Square - A square number is the product of two repeated integers.

  • Cube - A cube number is the product of three repeated integers.

  • Product - A product is the result of two or more numbers multiplied together.

During the explanation part of the lesson where examples of factors and multiples are given, let the students provide their own example of factors and multiples. Ensuring to state from their calculation, which are factors and which is the multiple.
