Grade 8 Mathematics Lesson Plan

Lesson Duration: 30 Minutes

Subject: Algebra

Topic: Solving Linear Equations

---

Objectives

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

1. Understand the concept of linear equations.
2. Solve single-variable linear equations.
3. Apply their understanding to real-world problems.

---

Materials Needed

• Whiteboard and markers
• Graph paper
• Worksheets with practice problems
• Calculators (optional)

---

Lesson Outline

Introduction (5 minutes)

• Begin with a brief discussion on what linear equations are.
• Share real-life examples of linear relationships (e.g., distance vs. time).
• Write the general form of a linear equation on the board: [ y = mx + b ]
• Explain the variables, coefficients, and constants.

Direct Instruction (10 minutes)

• Provide step-by-step instructions on how to solve a linear equation.
  • Example: Solve for ( x ): [ 2x + 3 = 11 ]
  • Step 1: Subtract 3 from both sides: ( 2x = 8 )
  • Step 2: Divide by 2: ( x = 4 )
• Solve a few more examples together with the class, ensuring to highlight the importance of maintaining balance in the equation.

Guided Practice (5 minutes)

• Distribute a worksheet with 2-3 linear equations for students to solve individually or in pairs:

1. ( 5x - 2 = 18 )
2. ( 4(x + 3) = 28 )

• Circulate the room to assist students as needed.

Independent Practice (5 minutes)

• Challenge students with an additional equation to solve on their own:

3. ( 3x + 7 = 22 )

Conclusion (5 minutes)

• Recap the key points discussed in the lesson.
• Address any lingering questions on solving linear equations.

Homework Assignment

Tasks

1. Solve the following linear equations: a) ( 6x - 4 = 26 )
   b) ( 2(x + 5) = 20 )
   c) ( 7 - 3x = 1 )

2. Write a short paragraph explaining how solving linear equations can be useful in real-life situations (e.g., budgeting, construction, etc.).

Answers

1. Solutions:

   • a) ( 6x - 4 = 26 )
     • Step 1: Add 4 to both sides: ( 6x = 30 )
     • Step 2: Divide by 6: ( x = 5 )
   • b) ( 2(x + 5) = 20 )
     • Step 1: Divide by 2: ( x + 5 = 10 )
     • Step 2: Subtract 5: ( x = 5 )
   • c) ( 7 - 3x = 1 )
     • Step 1: Subtract 7 from both sides: ( -3x = -6 )
     • Step 2: Divide by -3: ( x = 2 )

2. Short Paragraph Example: Solving linear equations is useful in real-life situations such as budgeting. For instance, if I have a fixed amount of money to spend each month and want to determine how much I can allocate to different expenses, I can set up an equation based on my income and expenses. By solving these equations, I can make informed financial decisions and ensure that I do not spend beyond my means.
