Lesson Structure

Introduction (5 Minutes)

• Begin by asking students if they have ever counted before. Discuss counting up and down.
• Introduce the number line as a tool that helps us visualize addition and subtraction.
• Show the number line on the board and explain how it works with visual aids.

Direct Instruction (10 Minutes)

• Explain addition on the number line:

  • Start at a number (e.g., 3).
  • Move forward to add (e.g., 3 + 2 by moving 2 spaces forward).
  • Write and show the equation on the whiteboard.

• Explain subtraction on the number line:

  • Start at a number (e.g., 5).
  • Move backward to subtract (e.g., 5 - 2 by moving 2 spaces back).
  • Write and show the equation on the whiteboard.

Guided Practice (5 Minutes)

• Provide each student with a number line worksheet.
• Give them simple addition problems (e.g., 1 + 2) and subtraction problems (e.g., 4 - 1).
• Ask students to draw lines or use counters as they solve the problems.

Independent Practice (5 Minutes)

• Allow students to complete a few more problems on their own:
  • Addition: 2 + 3, 4 + 1
  • Subtraction: 6 - 3, 5 - 2
• Walk around and offer assistance where needed.

Closure (5 Minutes)

• Review the key concepts:
  • How to use a number line for addition and subtraction.
  • Discuss answers with the class and correct any misunderstandings.
• Ask students to share their favorite part of the lesson.

Additional Notes

• Encourage students to practice using their number lines at home.
• Consider integrating technology by introducing math games that reinforce number line skills in future lessons.
