How to Teach a Child to Make Change With Money
Making change trains subtraction better than any worksheet. Here is a method from simple to advanced.
Why making change is the ideal subtraction trainer
The problem 100−67 feels abstract in a notebook. The same problem at a store is concrete: paid a hundred, the item costs 67, how much comes back? Real money gives instant feedback — get it wrong, and the change does not add up.
The "count up to round" method
How cashiers actually calculate
An item costs 67, paid with 100. A cashier does not subtract — they add up: "68, 69, 70" (three to reach 70), "80, 90, 100" (thirty more). Change — 33. This beats mental subtraction in speed.
Practice with play money
Paid 50, item 38 — change 12
Paid 100, item 45 — change 55
Paid 200, item 165 — change 35
The store game at home
Set up toys with price tags. The child takes turns as cashier and customer. The cashier role is especially useful — it demands calculating change on the spot, with no prep time.
FAQ
At what age should kids learn to make change?
Usually around age 7, once two-digit subtraction is solid.
What if a child keeps making mistakes?
Go back to smaller amounts and the "count up to round" method — it is easier than direct subtraction.
