**Lesson Plan: Solving Equations**
**Grade Level:** Junior Secondary 2
**Subject:** Mathematics
**Duration:** 60 minutes
**Topic:** Solving Equations
**Objectives:**
1. Students will understand the concept of an equation and the role of variables.
2. Students will learn how to solve simple linear equations.
3. Students will apply different methods for solving equations, including balancing and inverse operations.
4. Students will practice solving real-life problems involving equations.
**Materials Needed:**
- Whiteboard and markers
- Projector and laptop for presentation (optional)
- Handouts with practice problems
- Graphing paper
- Calculators (if necessary)

### **Introduction (10 minutes)**
1. **Greeting and Attendance (2 minutes):** Take attendance and greet the students.
2. **Warm-Up Activity (3 minutes):** Write the equation `x + 5 = 10` on the board and ask students what value `x` should be to make the equation true. Discuss briefly.
3. **Objective Overview (2 minutes):** Explain the objectives of the lesson and what students will learn.
4. **Quick Review (3 minutes):** Recap what students already know about variables and basic arithmetic operations.

### **Instruction (20 minutes)**
1. **Present the Concept (5 minutes):** Introduce the concept of an equation, explaining what variables and constants are.
- Example: An equation like `3x + 2 = 11`.
2. **Balancing Method (5 minutes):** Explain the balancing method for solving equations.
- Example: `3x + 2 = 11`
- Subtract 2 from both sides: `3x = 9`
- Divide both sides by 3: `x = 3`
3. **Inverse Operations (5 minutes):** Introduce the idea of using inverse operations to isolate the variable.
- Example: For the equation `2x - 4 = 10`,
- Add 4 to both sides: `2x = 14`
- Divide both sides by 2: `x = 7`
4. **Worked Examples (5 minutes):** Demonstrate a few more examples on the board involving both methods.
- Example: `4(x - 2) + 3 = 15`
- Subtract 3 from both sides: `4(x - 2) = 12`
- Divide by 4: `x - 2 = 3`
- Add 2 to both sides: `x = 5`

### **Guided Practice (15 minutes)**
1. **Group Activity (7 minutes):** Divide students into small groups and hand out practice problems. Each group solves a set of equations using either method taught.
- Example Problems:
- `5x + 7 = 22`
- `2x/3 = 6`
- `3(x + 4) = 21`
2. **Discussion (8 minutes):** Review the answers together and explain any common mistakes. Encourage students to present their step-by-step solutions to the class.
---
### **Independent Practice (10 minutes)**
1. **Worksheet Handout (10 minutes):** Give students a worksheet with a variety of linear equations to solve on their own.
- Examples:
- `7x - 5 = 16`
- `6x + 9 = 33`
- `x/4 - 2 = 3`
- `4(2x - 1) = 12`
2. **Peer Review:** Encourage students to work independently first, then pair up and compare answers with a classmate.
---
### **Conclusion (5 minutes)**
1. **Summary (2 minutes):** Summarize the key points of solving equations and the techniques used.
2. **Q&A (2 minutes):** Allow students to ask any remaining questions.
3. **Closing Remarks (1 minute):** Explain the next steps in their learning journey, such as homework assignment or the next lesson's topic. Encourage students to practice more at home.
**Homework:** Provide a set of additional problems for practice at home to reinforce what was taught in class.
**Assessment:**
- Observation during group activities and independent practice.
- Review of completed worksheets.
- Short quiz at the beginning of the next class to assess retention and understanding.
