When shopping you add up the prices.
How much does that cost together?
Add up all the prices: 2€ + 3€ = 5€
Working out the change:
You pay with a bill and get money back.
Example: the ice cream costs 3€. You pay with 5€.
5€ - 3€ = 2€ change
The filled in number shows the answer.
Example
- 5
What does this exercise practice?
This exercise connects addition and subtraction with a real situation and shows children that calculating is needed in everyday life.
Common pitfalls
With the change, children often forget to subtract instead of add. It helps to ask the question out loud: how much do I have to take away so I know what I get back?
How to practice at home
On the next trip to the supermarket, let the child add up two prices and check whether the result is right. Practice paying with real coins as long as you can.
