Lesson Plan: Positive and Negative Integers

Subject: Mathematics

Grade: 8

Duration: 30 Minutes

Topic: Positive and Negative Integers

---

Objective

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

• Understand the concept of positive and negative integers.
• Compare and order integers on a number line.
• Perform basic operations (addition and subtraction) with positive and negative integers.

Materials Needed

• Whiteboard and markers
• Number line chart
• Worksheets for practice and homework

---

Introduction (5 minutes)

1. Engage Students: Begin with a quick discussion on integers. Ask students:

   • What do they understand by the term "integer"?
   • Examples of positive and negative numbers in real life (e.g., temperature, banking).

2. Define Integers: Explain that integers include all whole numbers (both positive and negative) and zero:

   • Positive integers: 1, 2, 3, …
   • Negative integers: -1, -2, -3, …

---

Direct Instruction (10 minutes)

1. Number Line:
   Present a number line chart. Point out how integers are positioned relative to zero:

   • Explain that numbers to the right of zero are positive and those to the left are negative.

2. Comparing Integers:
   Demonstrate how to compare integers using symbols:

   • (5 > 3)
   • (-2 < 1)
   • (-4 > -10)

3. Basic Operations:
   Introduce the addition and subtraction of integers.

   • Addition:
     • Example: (3 + (-2) = 1)
     • Rule: If the signs are the same, add and keep the sign. If different, subtract and take the sign of the larger absolute value.
   • Subtraction:
     • Example: (5 - (-3) = 8)
     • Rule: To subtract a negative, add its positive.

Guided Practice (10 minutes)

1. Examples on the Board:
   Solve the following problems together as a class:

   • (7 + (-4))
   • (-3 + 5)
   • (2 - (-3))
   • (-6 - 3)

2. Student Participation:
   Ask students to volunteer to explain how they solved these problems. Facilitate and correct misunderstandings as needed.

---

Independent Practice (5 minutes)

Provide students with a worksheet containing problems on positive and negative integers, including comparisons and addition/subtraction.

Sample Problems:

1. Compare: ( -5) ___ (3) (Fill in with <, > or =)
2. Calculate: ( -2 + 7 = ?)
3. Calculate: ( -8 - 4 = ?)

---

Homework (5 minutes)

Assign the following homework to reinforce the lesson:

Homework Problems:

1. Compare: ( 2) ___ (-3)
2. Calculate: ( 6 + (-2) = ?)
3. Calculate: ( -1 - (-5) = ?)
4. Order the following integers from least to greatest: (-4, -1, 0, 2, -3)

Answers:

1. (2 > -3)
2. (6 + (-2) = 4)
3. (-1 - (-5) = 4)
4. Ordered: (-4, -3, -1, 0, 2)

Conclusion (2 minutes)

Wrap up the lesson by summarizing the key points:

• Understanding integers and their placement on a number line.
• How to compare, add, and subtract positive and negative integers. Encourage students to practice using integers in real-life situations and remind them to complete their homework.
