### Lesson Breakdown
#### Introduction (10 minutes)
1. **Greeting and Attendance:**
- Welcome students.
- Take attendance.
2. **Introduction to the Topic:**
- Explain the importance of building drawing in architecture and construction.
- Briefly discuss how building drawings serve as blueprints for constructing buildings.
#### Theoretical Overview (20 minutes)
1. **Basic Terminology:**
- Define key terms such as plan, elevation, section, scale, dimensions, and symbols.
2. **Types of Building Drawings:**
- Explain various types of building drawings and their purposes (e.g., floor plans, elevations, sections).
- Show examples of each type.
3. **Common Symbols and Conventions:**
- Introduce common symbols used in building drawings (e.g., electrical outlets, windows, doors).
- Discuss line types and what they represent (e.g., solid lines, dashed lines).
#### Practical Exercise: (25 minutes)
1. **Materials Needed:**
- Drawing paper or notebooks
- Drawing pencils (H, HB, 2H)
- Ruler, eraser, set squares
- Geometry box (compass, protractor)
2. **Drawing a Simple Floor Plan:**
- Guide students through drawing a simple floor plan of a small house.
- Include key features such as walls, doors, windows, and rooms.
- Emphasize the importance of scale and precision.
#### Class Discussion and Analysis (20 minutes)
1. **Review Student Drawings:**
- Collect student drawings and display them.
- Discuss and analyze the drawings, highlighting strengths and areas for improvement.
2. **Common Mistakes:**
- Discuss common mistakes students make when drawing floor plans and how to avoid them.
#### Conclusion and Q&A (10 minutes)
1. **Summary:**
- Recap the day's lesson and key points.
- Emphasize the significance of accuracy and neatness in building drawing.
2. **Questions and Answers:**

### Materials/Resources Needed:
- Whiteboard and markers or chalkboard and chalk
- Handouts with common symbols used in building drawing
- Examples of different types of building drawings
- Drawing tools: pencils, rulers, erasers, set squares, geometry boxes
### Assessment:
- Evaluate the practical exercise (floor plan) and assignment (elevation and section drawings) for precision, scale, use of symbols, and overall neatness.
- Provide feedback and offer additional support for students who need it.
### References:
- Textbook chapters on building drawing and architectural drafting
- Online resources or tutorials on technical drawing techniques
### Follow-Up:
In the next lesson, build on this foundation by introducing more complex concepts in building drawing, such as advanced drafting techniques, reading and interpreting professional blueprints, and introducing computer-aided design (CAD) software.
