## Lesson Plan: Revision on Freehand Sketching
### Grade Level: Senior Secondary 3
### Duration: 80 minutes
### Subject: Technical Drawing
### Objectives:
By the end of this lesson, students will be able to:
1. Recall and apply basic principles and techniques of freehand sketching.
2. Produce accurate freehand sketches of simple geometric shapes and everyday objects.
3. Develop spatial awareness and visualization skills.
### Materials Needed:
- Pencils (HB, 2B)
- Erasers
- Rulers (for reference, not usage during sketching)
- A4 drawing sheets
- Objects for sketching (e.g., geometric solids, simple household items)
- Whiteboard and markers
- Previous class notes and examples for reference
### Lesson Outline:
#### Introduction (10 minutes)
1. **Greeting and Roll Call:**
- Greeting the class and taking attendance.
2. **Review Objectives:**
- Briefly present the lesson objectives and outline the structure of the session.
3. **Recap Previous Knowledge:**
- Engage students in a quick discussion to recap basics: What is freehand sketching? Why is it important in technical drawing?
- Show a few examples of good sketches and discuss key elements that make them effective.
#### Instructional Input (20 minutes)
1. **Principles of Freehand Sketching:**
- Emphasize key principles: Proportion, Perspective, Lines, Shapes, Shading.
- Demonstrate basic techniques on the whiteboard, such as drawing straight lines, curves, circles, and simple geometric shapes.
2. **Visualization and Spatial Awareness:**
- Discuss the significance of visualizing objects before sketching.
- Introduce techniques for improving spatial awareness, such as mentally breaking down complex objects into simpler geometric forms.
#### Guided Practice (20 minutes)
1. **Sketching Simple Shapes:**
- Students practice sketching basic geometric shapes (squares, circles, triangles) as the teacher provides real-time feedback.
- Encourage students to focus on proportions and clean lines.
2. **Shading and Detailing:**
- Explain the basics of shading to add depth and dimension.
- Demonstrate how to add details to sketches without overcomplicating them.
#### Independent Practice (20 minutes)
1. **Sketching Everyday Objects:**
- Assign students to sketch selected everyday objects provided (e.g., a mug, a book, a pencil sharpener).
- Walk around to monitor progress, providing individualized guidance and support as needed.
2. **Peer Review:**
- Have students pair up and review each other's sketches, providing constructive feedback on accuracy, proportions, and detailing.
#### Conclusion (10 minutes)
1. **Review and Reflect:**
- Summarize key points covered during the lesson.
- Have students share their sketches and discuss what they found challenging or enjoyable.
2. **Homework Assignment:**
- Assign a homework task for students to sketch a more complex object or scene from their environment, applying the techniques learned in class.
3. **Q&A Session:**
- Open the floor for any questions or final clarifications.
### Assessment:
- **Formative:** Observations during guided and independent practice, feedback during peer review sessions.
- **Summative:** Evaluate the homework assignment based on criteria such as accuracy, proportion, shading, and overall presentation.
### Extension Activities:
- **Advanced Sketching Techniques:**
- Introduce more complex techniques such as different types of perspective (one-point, two-point).
- **Digital Sketching:**
- Encourage students with access to digital tools to explore digital freehand sketching applications.
### Reflection:
- After the lesson, take time to reflect on what went well and which areas could be improved. Note any particular challenges students faced and consider strategies to address them in future lessons.
