Mathematics Lesson Plan: Place Value

Grade Level: 2

Duration: 30 Minutes

Subject: Mathematics

Topic: Place Value

---

Lesson Overview

In this lesson, students will explore the concept of place value, understanding how the position of a digit affects its value in a number. The objective is to help students recognize and write two-digit numbers based on their place values (tens and ones).

Objectives

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

• Identify the place value of each digit in a two-digit number.
• Explain the importance of place value in understanding numbers.
• Write two-digit numbers using base-ten blocks and standard numeric form.

Materials Needed

• Base-ten blocks (tens rods and ones cubes)
• Whiteboard and markers
• Place value charts
• Worksheets for practice
• Interactive digital tools (optional)

Lesson Procedures

Introduction (5 minutes)

1. Engage Students: Begin with an engaging question:

   • "What happens if we change a number by moving a digit? Can someone give me an example?"

2. Connect Prior Knowledge: Briefly review the concept of numbers and counting from previous lessons. Ensure students understand single-digit numbers before transitioning to two-digit numbers.

Direct Instruction (10 minutes)

1. Introduce Place Value: Explain the concept of place value, focusing on the tens and ones places in two-digit numbers.

   • Example: Write the number 34 on the board. Explain:
     • The '3' is in the tens place, representing 30 (3 tens).
     • The '4' is in the ones place, representing 4 (4 ones).

2. Visual Aid: Show a place value chart on the board and fill it out together as a class. Use base-ten blocks to demonstrate how to visualize the numbers.

Guided Practice (10 minutes)

1. Hands-On Activity: Distribute base-ten blocks to each student or allow them to use virtual manipulatives online.

2. Group Work: In pairs, have students build different two-digit numbers using the blocks. Encourage them to say the numbers out loud as they build them, focusing on identifying the tens and ones.

3. Formative Assessment: Walk around to observe student interactions and understanding. Ask questions like:

   • "What number does your block represent?"
   • "How many tens and how many ones do you have?"

Independent Practice (5 minutes)

1. Worksheet Distribution: Hand out worksheets that feature various two-digit numbers.

   • Tasks may include identifying the place value of digits and matching numbers to their visual representations.

2. Quiet Work Time: Allow students to complete the worksheet independently. Provide support as needed.

Closing (5 minutes)

1. Review Key Concepts:

   • Ask students to share what they learned about place value today.
   • Reinforce the importance of understanding tens and ones.

2. Exit Ticket: As a quick assessment, ask each student to write down one two-digit number and identify the tens and ones. Collect these as they leave.

Differentiation

• For Advanced Learners: Provide challenges that involve three-digit numbers and have them identify the hundreds place as well.

• For Struggling Learners: Pair them with a partner or provide additional visuals and manipulatives to help them grasp the concept better.

Assessment

• Performance on the exit ticket will serve as an informal assessment of understanding.
• Collect worksheets to review and provide feedback on common mistakes or misunderstandings.
