Lesson Plan for Senior Secondary 2 - Technical Drawing - Introduction To Building Drawing

**Lesson Plan: Introduction to Building Drawing for Senior Secondary 2** **Objective:** By the end of the lesson, students will have an understanding of the basic concepts and components involved in building drawing, including common symbols, types of views, and basic drafting techniques. **Duration:** 90 minutes --- ### 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:** - Invite students to ask any questions they have about the lesson. #### Assignment (5 minutes) 1. **Homework:** - Assign students to draw a simple elevation and section of the house they drew in class. - Encourage them to use the symbols and conventions discussed. --- ### 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. --- **Note:** Adjustments may be needed based on class progress, available time, and student understanding. Ensure to provide individual support where necessary.
