Lesson Plan: Place Value in Mathematics

Grade Level

Grade 3

Subject

Mathematics

Duration

30 minutes

---

Learning Objectives

By the end of this lesson, students will be able to:

1. Understand the concept of place value in three-digit numbers.
2. Identify the value of each digit in a number.
3. Decompose and compose numbers using place value.

---

Materials Needed

• Whiteboard and markers
• Place value chart (printed handouts)
• Base ten blocks
• Worksheets for practice
• Pencils

---

Introduction (5 minutes)

• Begin the lesson by asking students what they know about numbers. Write a few examples on the board (e.g., 157, 304).
• Introduce the topic of place value, explaining that every digit in a number has a value based on its position.

---

Direct Instruction (10 minutes)

• Present the place value chart for numbers up to 1,000:

  • Hundreds, Tens, Ones

• Explain each place:

  • The hundreds place represents groups of 100.
  • The tens place represents groups of 10.
  • The ones place represents single units.

• Use a number from the board (e.g., 304):

  • Ask students to identify the value of each digit.
  • Break down 304:
    • 3 in the hundreds place = 300
    • 0 in the tens place = 0
    • 4 in the ones place = 4
  • Reinforce by writing the expanded form: 300 + 0 + 4.

• Demonstrate with base ten blocks how to represent numbers visually.

---

Guided Practice (10 minutes)

• Distribute the place value charts and base ten blocks to the students.

• Provide the number 246 and guide students:

  • Have them identify the digits and write their values.
  • Ask them to build the number with base ten blocks and explain their process to a partner.

• Walk around the classroom, assisting and encouraging discussion among students.

---

Independent Practice (3 minutes)

• Hand out a simple worksheet that includes:

  • Identifying the place value of different digits.
  • Writing numbers in expanded form.

• Ask students to complete the worksheet individually.

---

Closure (2 minutes)

• Recap the concept of place value and the importance of understanding how numbers are built.
• Ask a few students to share their answers from the worksheet.
• Reinforce that being able to break numbers apart helps in understanding math operations, such as addition and subtraction.

---

Assessment

• Monitor students during guided practice to assess understanding.
• Review the completed worksheets to evaluate individual student comprehension.

---

Extensions

• For students who grasp the concept quickly, provide challenges such as:

  • Creating their own numbers and asking classmates to find the expanded form.

• For students needing support, offer additional manipulatives or one-on-one assistance with smaller numbers.

By following this lesson plan, students will enhance their understanding of place value, which is foundational for their future studies in mathematics.
