When shopping you add up the prices.
How much does that cost together? Add up all the prices.
How much change do you get? Subtract the cost.
Example:
1. Cost: $2 + $3 = $5
2. Change: $10 - $5 = $5
Example
1. $5
For parents
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.
