Lesson details

Key learning points

  1. A common multiple is a multiple which is shared by 2 or more numbers

Common misconception

Pupils confuse the terminology of factors and multiples and mistake them for one another.

Spend time encouraging pupils to identify the factors in an array and within both multiplication and division equations. Make explicit that the product and dividend represent the multiple in each equation.

Keywords

  • Multiple - A multiple is the result of multiplying a number by an integer (not by a fraction).

  • Common multiple - A common multiple is a multiple that is common to two or more numbers.
