# Lesson Plan: Technical Drawing for SS1 - Development 2
## Subject: Technical Drawing
## Topic: Development 2
## Grade: Senior Secondary 1 (SS1)
## Duration: 80 minutes (double period)
### Objectives:
By the end of this lesson, students will be able to:
1. Understand the concept of development in technical drawing.
2. Identify different types of developments.
3. Create development drawings for basic geometric shapes.
### Materials Needed:
- Drawing boards
- T-squares
- Set squares
- Protractors
- Compasses
- Pencils (HB, 2B)
- Erasers
- A3/A4 drawing sheets
- Rulers
- Whiteboard/Chalkboard
- Markers/Chalk
- Example drawings of developments
### Lesson Structure:
#### Introduction (10 minutes)
1. **Greetings and Roll Call (2 minutes)**
2. **Introduction to the Topic (3 minutes)**
- Briefly explain what development in technical drawing means.
- Describe its importance in fields such as engineering, design, and architecture.
3. **Objectives Outline (5 minutes)**
- Outline what the students will learn and achieve by the end of the lesson.
#### Direct Instruction (20 minutes)
1. **Types of Developments (10 minutes)**
- Explain the different types of developments (Parallel and Radial).
- Show real-life examples where development is used (e.g., making a cardboard model, designing metal sheets).
2. **Development Techniques (10 minutes)**
- Demonstrate step-by-step how to draw developments of basic geometric shapes: cubes, prisms, cylinders, cones, and pyramids.
- Stress the importance of accuracy and neatness.
#### Guided Practice (20 minutes)
1. **Hands-On Activity (20 minutes)**
- Have students follow along step-by-step as you draw the development of a rectangular prism on the board.
- Check their progress continuously, providing help and feedback as needed.
#### Independent Practice (20 minutes)
1. **Individual Task (20 minutes)**
- Instruct students to create the developments for the following shapes independently:
1. Cube
2. Cylinder
3. Cone
- Monitor the classroom, offering individual support where necessary.
#### Conclusion (10 minutes)
1. **Review and Recap (5 minutes)**
- Summarize the main points covered in the lesson.
- Emphasize the importance of applying these techniques to real-world scenarios.
2. **Q&A Session (3 minutes)**
- Allow students to ask questions for clarification.
3. **Assignment (2 minutes)**
- Assign students to complete the development of a pyramid at home and bring it to the next class for review.
#### Assessment:
- Monitor students during guided and independent practice.
- Collect and review students’ independent tasks to assess their understanding.
- Check for accuracy, neatness, and comprehension in their assignment.
### Differentiation:
- Provide extra guidance and simplified instructions for students who may struggle with the concepts.
- Offer challenging tasks, such as more complex shapes, to students who grasp the concepts quickly.
### Reflection:
Post-lesson, reflect on the effectiveness of the lesson plan:
- Did students meet the learning objectives?
- Were the instructions clear and comprehensible?
- What improvements can be made for future lessons on this topic?
This lesson plan aims to build foundational skills in technical drawing while encouraging precision and creativity in creating accurate developmental drawings.
