Lesson 120: US Money - The Twenty-Dollar Bill

Directions

Gather one twenty-dollar bill, two ten-dollar bills, four five-dollar bills, and four one-dollar bills per child. Children might create their own pretend paper money with paper, pens, and crayons or markers.

Have children complete the steps below.

Have children practice until they perfectly master each task.

Steps

STEP 1 - WHAT IS A TWENTY-DOLLAR BILL?

Children identify the twenty-dollar bill.

• Direct the children to examine the front and back of the twenty-dollar bill. Ask the children to verbally describe what they see. Tell children there are also less common, larger denominations such as fifty-dollar bills, but we will not cover those.
• Have children hold up the twenty-dollar bill and recite, '1 twenty-dollar bill is worth 20 one-dollar bills.'

STEP 2 - COMBINE AND SEPARATE

Children combine and separate groups of one, five, ten, and twenty-dollar bills.

• Tell children to move 2 ten-dollar bills next to the twenty-dollar bill. Have them recite, '1 twenty-dollar bill is worth 2 ten-dollar bills.'
• Tell children to move 4 five-dollar bills next to the twenty-dollar bill. Have them recite, '1 twenty-dollar bill is worth 4 five-dollar bills.'

STEP 3 - PLAY STORE

• Give each child 1 twenty-dollar bill, 1 ten-dollar bill, 1 five-dollar bill, and 4 one-dollar bills. Say to children, 'A hair dryer costs 38 dollars. Show me which bills you must give to the cashier to purchase the dryer.'
• Give each child 1 twenty-dollar bill, 1 ten-dollar bill, 1 five-dollar bill, and 4 one-dollar bills. Say to children, 'A garden hose costs 36 dollars. Show me which bills you must give to the cashier to purchase the hose.'
• Give each child 1 twenty-dollar bill, 1 ten-dollar bill, 1 five-dollar bill, and 4 one-dollar bills. Say to children, 'A small plastic pool costs 34 dollars. Show me which bills you must give to the cashier to purchase the pool.'
