Base-Ten Money: Hundreds, Tens, and Ones

Explicit Instruction/Teacher modeling

• Choose a number between $100–$999. Write the amount down.
• Remind students that in a three-digit whole number, the digit on the left is the hundreds place, the digit in the middle is the tens place, and the digit on the right is the ones place.
• Ask for a student volunteer to project the given amount using the play money. Then ask how to write the number in expanded form. Record the answer under the given amount.
• Repeat the process with two different amounts.

Guided practise

• Distribute whiteboards and markers.
• Instruct students to write the letters H, T, and O in columns on the top of their board (to stand for hundreds, tens, and ones).
• Ask for a student volunteer to name an amount of money between $100–$999.
• Instruct students to write the number of hundreds, tens, and ones in the amount on their board. Have them turn their boards to face you.
• Write the number down on the chart paper, then repeat the above steps with three more student-led amounts.

Independent working time

• Distribute the Money & Place Value with Hundreds, Tens, and Ones worksheet.
• Read the instructions aloud and have a student volunteer read them back to you.
• Go over the example before instructing students to begin.
• Circulate the room while students are working, answering questions and informally assessing student abilities.
