Lesson Details
Key learning points
- When adding coins, the multiples of tens, then the ones, can be added to find the total amount.
- Counting on from the tens can also help to find the total.
- Knowledge of skip counting in twos can be used to count 20 p coins.
- The tens and ones in the total amount can be partitioned to help when using coins to make a given value .
- When the tens and ones digits in the total are the same, we can use the same number fact to find the coins to use.
Common misconception
When children are counting in steps of a given size, e.g. 2 p coins in twos, they may continue to count in twos when the coin changes.
Encourage children to notice the value of the coins they are counting and to check their work using known addition facts.
