### Lesson Outline
#### Day 1: Introduction to Orthographic Projection
1. **Introduction (10 minutes)**
- Start with a question: "What is orthographic projection?"
- Explain the purpose and importance in engineering and design.
- Introduce first-angle projection vs. third-angle projection.
2. **Presentation (20 minutes)**
- Use slides to show diagrams of first-angle orthographic projections.
- Illustrate how a 3D object is represented in 2D; discuss the views: front, top, and side.
- Explain the conventions and symbols used (e.g., the layout of views, dimension lines).
3. **Demonstration (15 minutes)**
- Demonstrate creating a simple first-angle orthographic projection of a cube on the whiteboard.
- Show how to label each view properly and include dimensions.
4. **Class Activity (5 minutes)**
- Hand out a simple object drawing worksheet for students to start practicing identifying views.

#### Day 2: Creating First Angle Orthographic Projections
1. **Review and Q&A (10 minutes)**
- Briefly review the previous lesson: key concepts and views of first angle orthographic projection.
- Answer any questions and clarify any points of confusion.
2. **Practical Exercise (30 minutes)**
- Provide each student with a simple 3D shape (either a physical object or a printed image).
- Students will sketch the front, top, and side views of the object in first angle orthographic projection using graph paper.
- Encourage students to use a ruler for straight lines and correct dimensioning.
- Teachers will circulate to provide feedback and assistance.
3. **Group Work (5 minutes)**
- Organize students into small groups to discuss their drawings.
- Have students compare their orthographic projections, encouraging constructive criticism.
4. **Closing (5 minutes)**
- Briefly recap the key points learned in both lessons.
- Assign the students to complete a homework exercise using a new object of their choice, creating its orthographic projection.
#### Assessment:
- Use a rubric to assess student drawings based on accuracy, clarity, and neatness.
- Homework should be assessed for understanding and the application of concepts learned in class.
#### Extension (Optional):
- Introduce software tools for digital drafting, such as CAD, to visualize how orthographic projections are used in professional settings.
- Students could explore more complex objects and practice dimensions further.
### Reflection:
- After the lesson, reflect on what worked well and what could be improved for future lessons.
