### Lesson Plan: Drawing Instruments and Materials
**Subject:** Basic Technology
**Grade:** Junior Secondary 1
**Duration:** 60 minutes
**Topic:** Drawing Instruments and Materials
#### Learning Objectives:
By the end of the lesson, students should be able to:
1. Identify various drawing instruments and materials.
2. Understand the use and care of drawing instruments.
3. Demonstrate basic drawing skills using identified instruments and materials.
#### Materials Needed:
- Whiteboard/Chalkboard
- Markers/Chalk
- Drawing instruments (Pencils, Rulers, Erasers, Compasses, Set Squares, T-Squares, Protractors)
- Drawing paper
- Sample technical drawings
#### Lesson Outline:
1. **Introduction (10 minutes):**
- Greet students and take attendance.
- Briefly discuss the importance of technical drawing in everyday life (e.g., in engineering, architecture, design).
- Introduce today's topic: "Drawing Instruments and Materials".
2. **Presentation (20 minutes):**
- **Identifying Drawing Instruments:**
- Show and explain each drawing instrument, demonstrating its use.
- Pencils: Different grades and their uses.
- Rulers: Types (e.g., straight edge, flexible) and uses.
- Erasers: Soft vs. hard erasers.
- Compasses: How to draw circles and arcs.
- Set Squares: Types (45-degree, 30/60-degree) and uses.
- T-Squares: For drawing horizontal lines.
- Protractors: Measuring and drawing angles.
- **Care of Instruments:**
- Discuss how to maintain and store the instruments to ensure longevity.
- Emphasize cleanliness and proper handling.
3. **Demonstration (10 minutes):**
- Perform a step-by-step demonstration of drawing a simple geometric figure (e.g., a rectangle with a diagonal line), using the instruments introduced.
- Explain each step as you go along.
- Encourage students to ask questions if they do not understand any step.
4. **Guided Practice (15 minutes):**
- Provide students with drawing paper and the necessary instruments.
- Instruct them to replicate the demonstrated drawing.
- Walk around the classroom, offering individual assistance and feedback.
5. **Conclusion (5 minutes):**
- Review the key points of the lesson.
- Ask a few students to explain the use of one or two instruments to solidify understanding.
- Assign a simple homework task: Draw three geometric shapes (circle, triangle, and square) using the instruments discussed.
#### Assessment:
- **Formative Assessment:** Observe students during guided practice, noting their ability to use the instruments correctly and any difficulties they encounter.
- **Student Reflection:** Ask students to share one new thing they learned about drawing instruments.
#### Homework/Extension Activities:
- Complete a simple geometric drawing at home.
- Write a short paragraph on why it is important to take care of drawing instruments.
#### Resources:
- Textbook: [Insert textbook name if available, otherwise mention any relevant online resources or handouts provided]
#### Notes:
- Ensure each student has access to the drawing instruments for hands-on practice.
- Encourage neatness and precision in their drawings for better technical drawing skills.
By the end of the lesson, the students will have a foundational understanding of drawing instruments and how to use them, setting the stage for more complex drawings in future lessons.
