Multiplication as repeated addition

Mathematics · Multiplication & Division · conceptual

Understand multiplication as repeated addition and grouping equal sets

What mastery looks like

  • Explain that 3 groups of 2 is the same as 2 + 2 + 2
  • Use objects to make equal groups and count the total
  • Recognise an array as showing equal rows

Check your understanding

If Multiplication as repeated addition needs to count 4 bags with 3 apples in each, can they see that instead of counting all 12 one by one, they could add 3 + 3 + 3 + 3 — or say '4 groups of 3'?
