Subject: Mathematics
Topic: Place Value
Duration: 30 minutes
Class Level: Doesn't matter
Learning Objectives
By the end of this lesson, students will be able to:
- Understand the concept of place value in numbers.
- Identify the value of digits in multi-digit numbers.
- Use place value to compare and order numbers.
Materials Needed
- Whiteboard and markers
- Place value charts
- Number cards (0-9)

Lesson Outline
Introduction (5 minutes)
- Begin with a brief explanation of what place value is: "Place value refers to the value of a digit based on its position within a number."
- Provide simple examples using one-digit and two-digit numbers.
Direct Instruction (10 minutes)
-
Place Value Definition:
- Explain how each digit in a number has a different value depending on its position.
- Introduce the terms ones, tens, hundreds, etc.
-
Use of Place Value Charts:
- Demonstrate how to read and write numbers using a place value chart.
- Example: Show the number 345, explaining that 3 is in the hundreds place, 4 in the tens place, and 5 in the ones place.
Guided Practice (10 minutes)
- Together with the students, fill out a place value chart for the number 672.
- Ask students to identify the place value of each digit.
- Hold a small discussion on how changes in the digits affect the overall value of the number.
Independent Practice (5 minutes)
- Distribute a worksheet with practice problems where students need to identify the place value of given digits in multi-digit numbers.
Recap and Conclusion (5 minutes)
- Briefly recap what was covered in the lesson.
- Ask students questions such as:
- "What place is the digit 6 in the number 1678?"
- "How does changing the tens digit affect the overall number?"
