Lesson details

Key learning points

  1. A multiplication equation can be written to solve division problems.
  2. A division equation can be written to solve division problems.
  3. The number of equal groups in a number can be found by counting forwards.
  4. The number of equal groups in a number can be found by counting backwards.
  5. Counting forwards is usually easier because multiplication facts can be used to help.

Common misconception

Children may not understand division as repeated subtraction because they can count forwards to find the number of equal groups in a number.

On a number line, show how counting forwards and backwards in multiples results in the same answer. Discuss the difficulty of using tables facts to count backwards when there is a remainder, so they understand why counting forwards is more efficient.

Keywords

  • Grouping - Grouping is when we divide a number of objects into equal groups. We know the total number of objects and the number of objects in each group, but we do not know how many equal groups there are.

  • Division - Division means splitting into equal parts or groups

  • Divisor - The divisor is what we are dividing by.

  • Remainder - A remainder is the amount left over after division when the dividend does not divide exactly by the divisor.

It is important that children develop their understanding by working practically, so wherever possible, encourage children to act out the scenarios given in the slide deck and adapt slightly to create other grouping problems to act out.

Q2.
Match the multiplication and division equations that can represent the same number of groups.
Correct Answer:2 × 9 = 18,18 ÷ 9 = 2

18 ÷ 9 = 2

Correct Answer:6 × 7 = 42,42 ÷ 7 = 6

42 ÷ 7 = 6

Correct Answer:5 × 8 = 40,40 ÷ 8 = 5

40 ÷ 8 = 5

Correct Answer:7 × 4 = 28,28 ÷ 4 = 7

28 ÷ 4 = 7

Q3.
