## Lesson Plan: Board Practices and Scale Drawing
### Class Details
- **Grade Level:** Junior Secondary 1
- **Subject:** Basic Technology
- **Duration:** 40 minutes
### Learning Objectives
By the end of this lesson, students will be able to:
1. Understand the basics of board practice.
2. Differentiate between different types of drawing boards and their uses.
3. Understand the concept of scale in drawing.
4. Demonstrate the ability to create a basic scale drawing.
### Materials Needed
- Drawing boards or alternative flat surfaces
- Drawing paper
- T-squares
- Set squares
- Scale rulers
- Pencils and erasers
- Compass
- Chalk and board or whiteboard and markers.
### Lesson Flow
#### 1. Introduction (5 minutes)
**a. Welcome and Introduction:**
- Welcome the students to the class.
- Introduce the topic: "Board Practices and Scale Drawing."
**b. Engage:**
- Ask students if anyone has seen an architect or engineer's drawing before.
- Show them a simple scale drawing and explain its real-life applications.
#### 2. Explanation and Demonstration (10 minutes)
**a. Board Practices:**
- Explain the importance of using a drawing board for technical drawings.
- Show different drawing instruments (T-square, set squares,-compass) and their use.
- Demonstrate how to attach the drawing paper to the drawing board.
**b. Scale Drawing:**
- Define "scale" in the context of technical drawing.
- Explain how scale is used to represent large objects on a smaller drawing paper.
- Show examples of common scales (e.g., 1:10, 1:50).
- Demonstrate how to convert real measurements into scaled drawings using a scale ruler.
#### 3. Guided Practice (10 minutes)
**a. Setting Up:**
- Provide each student with drawing materials.
- Guide students to properly set up their drawing boards and attach their papers.
**b. Simple Scale Drawing:**
- Provide a simple object or shape (e.g., a rectangle or room layout).
- Guide students step-by-step to draw the object to scale.
- Encourage accuracy and neatness in their drawings.
#### 4. Independent Practice (10 minutes)
- Ask students to create a scale drawing of their choice (e.g., a book, table, or a simple floor plan) using a scale of 1:20.
- Walk around the classroom to provide individual support and ensure students are correctly applying the concepts.
#### 5. Review and Conclusion (5 minutes)
- Review key points of the lesson:
- Importance and use of drawing boards and tools.
- Understanding and using scales in technical drawings.
- Ask a few students to present their scale drawings to the class.
- Provide positive feedback and correct any common mistakes.
- Conclude the lesson by summarizing what was learned.
- Assign a simple homework task to reinforce the day's lesson (e.g., "Draw your favorite object to scale").
#### Assessment
- Observe students during guided and independent practice to assess their understanding and application of scale drawing.
- Collect and review their drawings to ensure accuracy and understanding of the concepts taught.
### Differentiation
- For students who grasp the concepts quickly, provide a more complex object to draw to scale.
- For students who struggle, offer additional one-on-one guidance and simplify the drawing task.
### Extension
- Encourage interested students to explore more advanced technical drawing techniques in their free time.
- Suggest online resources or textbooks where they can learn more about board practices and scale drawing.
### Follow-Up
- Plan a follow-up lesson to build on these skills, introducing more complex shapes and larger-scale drawings.
- Consider incorporating technology by using drawing software in future lessons.
