How to Teach Money and Coins

4 min readK2nd

Money is one of the most practical math topics — and one of the most confusing for young children. A dime is smaller than a nickel but worth more. A quarter is worth 25 cents, which is not an easy skip-counting number. And making change requires subtraction across denominations.

Here is how to teach money math in the order that builds understanding.

Stage 1: Identify the coins

Before counting values, your child must recognize each coin by sight:

CoinValueKey feature
PennyCopper colored, smallest value
NickelLarger than a dime, smooth edge
Dime10¢Smallest coin, ridged edge
Quarter25¢Largest common coin, ridged edge

The dime is the tricky one — it is the smallest coin but not the least valuable. Address this directly: "In money, size does not equal value. The dime is small but worth 10 cents."

Stage 2: Count single coin types

Start by counting groups of the same coin:

  • Pennies: Count by 1s. "5 pennies = 5 cents."
  • Nickels: Count by 5s. "4 nickels: 5, 10, 15, 20 cents."
  • Dimes: Count by 10s. "3 dimes: 10, 20, 30 cents."
  • Quarters: Count by 25s. "3 quarters: 25, 50, 75 cents."

This is where skip counting directly pays off. A child who can count by 5s and 10s fluently will handle nickels and dimes easily.

Stage 3: Count mixed coins

Now combine different coin types. The key strategy: sort first, then count largest to smallest.

"You have 2 quarters, 1 dime, 1 nickel, and 3 pennies."

  • Start with quarters: 25, 50
  • Add the dime: 60
  • Add the nickel: 65
  • Add the pennies: 66, 67, 68

Total: 68 cents.

Key Insight: Always count from the highest-value coin to the lowest. This minimizes the number of skip-counting transitions and reduces errors. If your child counts pennies first and then tries to add a quarter, the arithmetic is harder.

Stage 4: Making amounts

"Show me 47 cents using the fewest coins."

This requires thinking about combinations:

  • 1 quarter (25¢) + 2 dimes (20¢) + 2 pennies (2¢) = 47¢

This is a practical skill and also reinforces place value thinking — building amounts from different denominations is similar to building numbers from hundreds, tens, and ones.

Stage 5: Making change

Making change is subtraction in context:

"You buy something for 63 cents. You pay with $1.00. How much change?"

Count-up method: "Start at 63. Count up to 100: 63 + 2 pennies = 65. Plus 1 dime = 75. Plus 1 quarter = 100. Change: 2 + 10 + 25 = 37 cents."

Subtraction method: "100 - 63 = 37 cents."

The count-up method is more practical — it is what cashiers actually do — and avoids the need for regrouping across the decimal.

Dollars and cents

When your child is comfortable with coins, extend to dollars:

  • $1.00 = 100 cents
  • Prices combine dollars and cents: $3.47 means 3 dollars and 47 cents
  • Adding prices: $2.50 + $1.75 = $4.25 (this is decimal addition in disguise)

The dollar sign and decimal point are just notation for a concept your child already understands from coin counting.

Common mistakes

Counting by the wrong skip number: They count nickels by 1s or dimes by 5s. Practice each coin's skip pattern in isolation first.

Starting with the smallest coin: They count pennies first and get confused when adding larger coins. Teach the "largest first" strategy.

Thinking bigger coins = more value: They think 5 pennies are worth more than 1 nickel because there are more of them. Use direct comparison: trade 5 pennies for 1 nickel.

Confusing the cent symbol and dollar sign: Practice notation: 47¢ or $0.47 — same amount, different notation.


Money math is one of the few topics where children immediately see the real-world application. Use real coins whenever possible. Practice at the store, at the lemonade stand, at the piggy bank. When money concepts are solid, your child has practiced skip counting, addition, subtraction, and decimal concepts all at once.

If you want a system that integrates money concepts into the math progression — connecting them to the skip counting and place value skills they depend on — that is what Lumastery does.
