Lesson details
Learning outcome
I can find the most efficient way to make a given value.
Key learning points
- £2 coins, £5 notes, £10 notes and £20 notes can be used to pay for items in pounds.
- It is more efficient to pay for items using fewer coins or notes.
- When deciding how to pay efficiently, the tens and the ones in the price can be we can partitioned to help us.
- When making a given value, it is more efficient to use coins or notes with a greater value when you can.
Keywords
Efficient - Not wasting time or effort. An efficient strategy is one we can carry out easily.
Value - Where referring to money, value refers to how much something is worth.
Common misconception
Because children are focusing their attention on the values of the coins, they may revert to inefficient strategies when adding coins.
Model and draw attention to efficient strategies for addition as coins and notes are added, such as the use of doubles, multiplication facts or strategies for adding more than two numbers.
Teacher tip
When making values with different coins and notes, encourage children to work logically, thinking about the coins or notes with the greatest value first.
