Lesson details

Key learning points

  1. Coins can be added in any order and the total value will remain the same.
  2. It can be easier to add coins if you move them, group together coins of the same value or start with the greatest value.
  3. When adding coins, you can use strategies you already know to help you add efficiently.
  4. It is more efficient to use fewer coins of greater value than a greater number of lower value coins.

Common misconception

Children may start counting out using any coins available instead of thinking of the whole amount needed first and partitioning it into manageable parts where they can deploy known strategies.

Encourage children to use what they know about making 10, and the numbers up to 10, to find combinations that use the fewest possible coins to total a given value.

Keywords

  • Total value - Where referring to money, value refers to how much something is worth. The total value can be found by adding the value of each coin in a set.

  • Efficiently - Not wasting time or effort. An efficient strategy is one we can carry out easily.

This lesson brings together knowledge from many units, including the composition of number. Explore these ideas practically, manipulating coins within known part-part-whole models to help children connect these ideas with existing knowledge and understanding.
