Financial Literacy — Coin Values and Exchanges
Warm-up
I will show you some nickels. Count their total value. Show 2 nickels (10 cents), 4 nickels (20 cents), 7 nickels (35 cents). What are you doing in your head? (Skip-counting by 5s.) Now dimes. Connect explicitly: counting coins uses skip-counting you already know.
Explore
Classroom store with items priced in whole numbers of cents (5, 10, 25, 50 cents, 1 dollar). Students shop with a set of coins, select items, and count coins to pay. Then role-play a trade game using shells and beads with assigned values. Students negotiate trades and reason about equivalent value.
Consolidate
Practice
Students complete a coin-counting sheet (count multiples of each denomination) and a shopping scenario (select items totalling exactly 1 dollar using different coin combinations). Exit ticket: show me 30 cents using only dimes. How many? (3.)

6 nickels times 5 cents = 30 cents. Not quite enough. Count with the student: 5, 10, 15, 20, 25, 30. We only reached 30 cents. How much more do we need? (5 cents more, one more nickel.)
The quarter is smaller in size but worth more in value. Let us check: how many pennies is a dime worth? (10.) How many is a quarter worth? (25.) Which is worth more? Value is not determined by size. It is an agreed-upon convention.
