Vocabulary
Ones place: The digit in the rightmost position of a number.
Tens place: The digit in the second rightmost position of a number.
Hundreds place: The digit in the leftmost position of a number.
Identify Digits (up to Hundreds Place)
Prerequisite Skill
Materials and Preparation
- Place-value chart
- Number cards
- Markers or pencils
- Worksheet pack (guided practice, independent practice, exit tickets, homework, assessment)
Learning Objectives
- Students will understand and identify the place value of digits in a three-digit number.
- Students will be able to determine which digit is in the ones place, which digit is in the tens place, and which digit is in the hundreds place.
Introduction
Introduce the concept of place value by explaining that each digit in a number has a different value depending on its position. Use the number 193 as an example. Write it on the board and highlight the digits.
Explicit Instruction/Teacher modeling
Explain that in the number 193, the 3 is in the ones place, the 9 is in the tens place, and the 1 is in the hundreds place. Use a place-value chart to visually represent this:
hundreds tens ones
1 9 3
Guided Practice
Provide students with several two-digit numbers and place-value charts. Work together as a class to fill in the charts and identify the digits in the ones, tens, and hundreds places.
Independent Practice
Hand out worksheets with three-digit numbers. Have students use place-value charts to determine which digit is in the ones place, which is in the tens place, and which is in the hundreds place for each number.
Differentiation
Support
- Provide additional place-value charts for students to reference.
- Pair students for peer support.
- Offer additional practice worksheets for students who need extra help.
Extension
- Reading: Read a math story that involves place value and ask students to identify the place value of digits in the numbers mentioned.
- Writing: Have students write their three-digit numbers and identify the digits in the ones, tens, and hundreds places.
Assessment
Use an assessment worksheet from the worksheet pack to evaluate students' understanding of place value. The worksheet will include several three-digit numbers where students must identify the digits in the ones and tens places.
Review and closing
Review the key idea that each digit in a number has a different value depending on its position. Address any common misconceptions, such as confusing the ones and tens places. Allow students to ask any final questions and share their observations.
Misconceptions
- Confusing Ones and Tens: Students might confuse the ones and tens places. Reinforce the position of each place using the place-value chart.
- Value Misunderstanding: Students might think the value of a digit does not change with its position. Clarify that the position determines the value.
