Lesson Plan for Junior Secondary 1 - Basic Tech - Drawing Instruments And Materials

### 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.
