Lesson details
Key learning points
- Coins can be added in any order, but it is more efficient to group coins of the same value together.
- It is more efficient to add the greatest value coins first, or find coins that will help with using a mental strategy.
- When adding coins, known strategies can be used to help add efficiently.
- A number line can be used to help keep track of the coins added.
Common misconception
Children may start counting with the first coin they see or arranged them in a line in no particular order, leading to inefficient counting strategies instead of more efficient calculation methods.
Encourage children to group coins of the same value together and start with higher value coins, so they can apply the calculation strategies they already know to find the total value of a set of different coins.
Keywords
Efficiently - Not wasting time or effort. An efficient strategy is one we can carry out easily.
