Lesson Plan: Types of Numbers, the Number Line, Positive and Negative Numbers, Absolute Value

Subject: Mathematics

Grade Level: 7

Duration: 30 Minutes

---

Lesson Objectives

• Students will understand different types of numbers (whole numbers, integers, rational numbers).
• Students will learn how to represent positive and negative numbers on a number line.
• Students will grasp the concept of absolute value and its significance.

Materials Needed

• Whiteboard and markers
• Printed worksheets
• Rulers
• Graph paper
• Projector (optional)

Lesson Outline

Introduction (5 minutes)

• Begin with a brief discussion on numbers. Ask students to share examples of different types of numbers they know.
• Introduce the terms:
  • Whole numbers
  • Integers
  • Rational numbers
• Explain that all these numbers can be represented on a number line.

Types of Numbers (10 minutes)

• Discuss the types of numbers using visual aids.
  • Whole Numbers: 0, 1, 2, 3, ...
  • Integers: ...,-3, -2, -1, 0, 1, 2, 3, ...
  • Rational Numbers: Numbers that can be expressed as fractions.

The Number Line (5 minutes)

• Draw a number line on the board.
• Mark the integers on the number line, ensuring to include both positive and negative integers.
• Show how to locate points for positive numbers on the right and negative numbers on the left.

Positive and Negative Numbers (5 minutes)

• Explain the concept of positive and negative numbers using real-life examples.
• Discuss their applications, such as temperature, altitude, and financial contexts.
• Ask students to identify positive and negative numbers in everyday life.

Absolute Value (5 minutes)

• Introduce the absolute value concept by explaining that it represents the distance of a number from zero on a number line.
• Use the following notation: |x|, where x is the number.

Examples:

• |3| = 3
• |-3| = 3

Guided Practice (5 minutes)

• Distribute worksheets for students to practice representing numbers on a number line and calculating absolute values.
• Walk around to provide assistance as students work through problems.
