Concept Development Part 1 What is the value of the coins on this slide?

Concept Development What is the value of the coins on this slide? So the coins on both slides are equal in value? You can use different coins to make the same value.

Concept Development With a partner, show 28 cents two different ways. Repeat with 56 cents, 75 cents, and 1 dollar.

Concept Development Part 2 Problem 1: Tony gets 83 cents change back form the cashier at the corner store. What coins might Tony have received? Write your coin combinations and the total value below your drawing.

Debrief Look at your partner’s coin combinations for 26 cents. Did you use the same combinations as your partner. Look at Problem 2, 35 cents. With your partner, think about how you could make 35 cents using the least number of coins. How could you make 35 cents using the largest number of coins?

Debrief Can you think of other math skills we have learned where the same value can be represented in different ways? With your partner, find all the different coin combinations for 15 cents.
