# Lesson Plan for Basic Tech (Junior Secondary 2)
## Topic: Area of Plane Figures
### General Information
- **Grade Level**: Junior Secondary 2
- **Duration**: 60 minutes
- **Subject**: Basic Technology
### Objectives
By the end of the lesson, students should be able to:
1. Define plane figures.
2. Identify different types of plane figures.
3. Apply formulas to calculate the area of various plane figures.
4. Solve real-life problems involving the area of plane figures.
### Materials
- Whiteboard and markers
- Geometry sets (rulers, compasses, protractors)
- Graph paper
- Printed worksheets with plane figures
- Calculator
### Lesson Outline
#### Introduction (10 minutes)
1. **Greeting and Attendance (2 minutes)**:
- Quick welcome and attendance check.
2. **Review Previous Knowledge (3 minutes)**:
- Briefly review concepts of perimeter and common geometric shapes.
3. **Objective Introduction (5 minutes)**:
- Explain today's objectives.
- Define plane figures (2D shapes with length and breadth).
#### Direct Instruction (15 minutes)
1. **Types of Plane Figures**:
- List and show visuals of common plane figures such as squares, rectangles, triangles, and circles.
2. **Formulas to Calculate Area**:
- Present and write down the area formulas:
- Square: Area = side²
- Rectangle: Area = length × width
- Triangle: Area = ½ × base × height
- Circle: Area = π × radius² (introduce π as approximately 3.14)
3. **Worked Examples**:
- Solve example problems on the board:
- Find the area of a rectangle with length 5 cm and width 3 cm.
- Calculate the area of a triangle with base 4 cm and height 5 cm.
- Determine the area of a circle with radius 3 cm.
#### Guided Practice (15 minutes)
1. **Class Activity**:
- Provide students with printed worksheets that have various plane figures.
- Work together to solve a few problems as a class.
- Discuss each step clearly to ensure understanding.
#### Independent Practice (10 minutes)
1. **Student Exercise**:
- Assign additional problems from the worksheet for students to solve individually.
- Circulate the room to provide support as needed.
#### Real-Life Application (5 minutes)
1. **Discuss Practical Uses**:
- Open a discussion about how the knowledge of the area is useful in real life (e.g., finding the area of a floor to lay tiles, determining the surface area for painting).
#### Conclusion (5 minutes)
1. **Review**:
- Recap what has been learned during the lesson.
2. **Exit Ticket**:
- Students write one thing they learned and one question they still have on a piece of paper before leaving.
### Assessment
- **Formative**: Student participation during guided practice, and teacher observations.
- **Summative**: Student performance on the independent practice problems and the exit ticket.
### Homework
- Assign a few problems involving the calculation of the areas of different plane figures to reinforce lesson concepts.
### Reflection
- After the lesson, evaluate what went well and what needs improvement. Adjust future lesson plans accordingly to address any gaps in student understanding or engagement.
