Structured Activity 1: War!

Materials Needed:
  • paper
  • pencil
  • money cards (below)

Concepts that will be covered during the activity: Students will be able to determine the value of mixed coins and bills up to $50

Instructions: Cut out the boxes showing coins and bills below. Each of the players chooses a group of coins and bills at random (without looking). Determine how much money is shown and write it on the card. The player with the greatest amount of money wins the round and gets the two cards added back to his/her deck. Play until one person has all the cards.



















Parent prompt: We are going to play war. We each get 5 of these cards. Mix them up without looking and put them in a pile upside-down in front of you. We will each play one card, and whoever has the greatest amount of money showing wins the round. Flip over your first card and count up how much money the card is worth.

Student response: (Responses will vary) E.g., I have 1 twenty Dollar bill, 3 nickels, 1 one dollar bill, 6 pennies, and 3 quarters.



The 20 dollar bill makes 20, plus 3 nickels, or $0.15, is $20.15.
Add another dollar, and it's $21.15.
Add 6 pennies, and I have $21.21.
Add 3 quarters, or $0.75, and it is $21.96.

Parent prompt: (Responses will vary) E.g., My card has 1 Ten dollar bill, 1 Dime, 2 five dollar bills, 2 nickels, and 7 pennies.



My total is 10 plus a dime equals $10.10.
Add 2 five dollar bills, or $10, and it is $20.10.
2 nickels makes $20.20.
7 pennies make the total $20.27. You win this round. Take the cards. Then we'll each turn another card over. Add up the total of your new card.

Student response: (Responses will vary) E.g., My card has 3 ten dollar bills, 2 quarters, and 8 dimes.



3 ten dollar bills equals $30.00.
Adding 2 quarters, or $0.50, makes it $30.50.
8 dimes make it $31.30.

Parent prompt: (Responses will vary) E.g., I have 1 Twenty dollar bill, 3 dimes, 2 nickels, 1 ten dollar bill, 1 Five dollar bill, and 4 pennies.



My amount is 20 plus 3 dimes, or $0.30, equals $20.30.
Add 2 nickels, and I have $20.40.
A ten dollar bill makes $30.40.
A five dollar bill gives me $35.40.
4 pennies make it $35.44. I win this round so I get the cards. We'll each flip another new card over. What is the total on your card?

Student response: (Responses will vary) E.g., I flipped over a card with 2 one dollar bills, 2 dimes, and 2 quarters.



I have $2 plus 2 dimes, or $0.20, which makes $2.20.
Add the 2 quarters, or $0.50, and I have $2.70. Not much!

Parent prompt: (Responses will vary) E.g., My card has 1 one dollar bill, 3 quarters, 1 dime, and 1 ten dollar bill.



A dollar plus 3 quarters equals $1.75.
Plus a dime is $1.85.
Add a ten dollar bill, and I have $11.85. I win this round too. Hand me the cards and flip over a new one.

Student response: (Responses will vary) E.g., This round, I have a card with 1 Penny, 1 Quarter, 2 twenty dollar bills, and 3 dimes.



I have one cent plus a quarter, which equals $0.26.
Plus 2 twenty dollar bills makes it $40.26.
Add 3 dimes, and I have $40.56.

Parent prompt: (Responses will vary) E.g., My card has 1 five dollar bill, 1 penny, 1 one dollar bill, and 1 dime.



A five dollar bill and a penny make $5.01.
Add a dollar, and I have $6.01.
Add a dime, and I have $6.11. You win this round; here's my card. Flip a new card.

Student response: (Responses will vary) E.g., I have 1 quarter, 2 dimes, 6 pennies, 2 twenty dollar bills, 2 nickels, and 3 one dollar bills.



The quarter plus two dimes is $0.45.
6 pennies added makes $0.51.

Structured Activity 2: Same but Different Part I

Materials Needed:
  • paper
  • pencil

Concepts that will be covered during the activity: Students will be able to determine the value of mixed coins and bills up to $50

Instructions: Shown below are several groups of money. Match the cards that show the same amount.

















Parent prompt: We need to match the boxes numbered 1-4 with the boxes lettered A-D that have the same amount of money in them. Let's begin with Box 1. What is shown in that box?

Student response: Box 1 shows a twenty dollar bill, a dime, a ten dollar bill, a Nickel, 2 one dollar bills, and a penny.

Add the penny, and Box 1 has $32.16.

Parent prompt: Look at Boxes A-D. Which box do you think might have $32.16 in it?

Student response: (Responses will vary) E.g., Only boxes A and B have the right number of pennies in them to make 16 cents. Box C doesn't have any pennies so it can't make 16 cents. Box D has 2 pennies so it can only make 2 cents or 7 cents, not 6. I will try box B.

Parent prompt: How much money is shown in Box B?

Student response: Box B shows 3 ten dollar bills, 4 dimes, 2 quarters, a one dollar bill, a penny, and 5 nickels.



3 ten dollar bills make $30.
Add 4 dimes, or $0.40, and it's $30.40.
2 quarters add 50 cents so that's $30.90.
The one dollar bill makes it $31.90.
An added penny makes it $31.91.
5 nickels add 25 cents, which makes $32.16. That is the same as Box 1.

Parent prompt: Box 1 matches Box B. Try Box 2 now. What is in Box 2?

Student response: Box 2 shows a twenty dollar bill, a quarter, 4 nickels, 2 dimes, 4 one dollar bills, and 5 pennies.



The twenty dollar bill plus a quarter is $20.25.

2 dimes add another $0.20, for $20.65.
The 4 one dollar bills make the total $24.65.
Add the 5 pennies, and Box 2 has $24.70.

Parent prompt: Look at Boxes A, C, and D. Which box do you think might have $24.70 in it?

Student response: (Responses will vary) E.g., Box A has one penny so it will make either 1 cent or 6 cents. It cannot make 70 cents. Box C doesn't have any pennies so it can make 70 cents. Box D has 2 pennies so it can only make 2 cents or 7 cents, not 70. I will try box C.

Parent prompt: How much money is shown in box C?

Student response: Box C shows 2 ten dollar bills, 2 dimes, 10 quarters, and 2 one dollar bills.



2 ten dollar bills make $20.
