Try with real coins

Try coins with a grown-up. Make the same amount two different ways.

For a grown-up

Let your child find the first action. Ask them to make the same amount using a different number of coins, then explain why the value stayed the same. The labelled cards teach counting values; they do not check recognition of unlabelled real coins.
