Multiply by Multiples of 10: how to help at home or in class
Coins make tens concrete. Lay out 3 groups of 4 dimes and ask how many dimes there are in all, then how many cents that is. Twelve dimes is 120 cents, which matches 3 × 40. Try a handful of other groups, each time saying the small fact first and the money value second. When your child states the base fact before the final answer without prompting, finding missing factors with tens comes next.
