**Topic**: Lettering: Types and Styles
---
**Objective**:
- To introduce students to the concept of lettering in technical drawing.
- To teach students the different types and styles of lettering used in technical drawings.
- To develop students' skills in precise and legible lettering for technical documents.
**Duration**: 60 minutes
**Materials Needed**:
- Drawing paper or sketchbooks
- Pencils (HB and 2B)
- Erasers
- Rulers
- Technical drawing set squares
- Example sheets of different lettering styles
- Whiteboard and markers
- Projector/screen (if available)
**Introduction (10 minutes)**:
1. **Greeting and Roll Call** (2 minutes)
- Greet the students and take attendance.
2. **Introduction to Lettering** (8 minutes)
- Explain what lettering is and why it is important in technical drawings.
- Show examples of technical drawings with well-executed lettering.
- Briefly discuss the importance of neatness, spacing, and legibility.
**Lesson Development (40 minutes)**:
1. **Types of Lettering** (10 minutes)
- Discuss the various types of lettering:
- **Single-stroke Gothic**: Simple and commonly used in technical drawings.
- **Roman**: More ornate, less common in technical contexts.
- Use the projector/screen or whiteboard to illustrate examples of each type.
2. **Styles of Lettering** (10 minutes)
- Explain different styles used within the types, primarily focusing on upper-case and lower-case variations.
- Discuss aligned (horizontal, vertical) and slanted (italic) styles.
- Show examples using the projector/screen or whiteboard.
3. **Characteristics of Good Lettering** (5 minutes)
- Emphasize uniform height, consistent spacing between letters and words, and clarity.
- Discuss the standard height ratio for technical lettering - typically 3 mm for lowercase and 4-5 mm for uppercase in most drawings.
4. **Demonstration of Lettering Techniques** (15 minutes)
- Demonstrate the correct way to hold a pencil and position a ruler to achieve neat lines.
- Show how to draw guide lines lightly to maintain consistent letter height and alignment.
- Write examples of both types and styles on the whiteboard while explaining the steps.
5. **Student Practice** (10 minutes)
- Distribute drawing paper/sketchbooks and pencils.
- Have students practice lettering the alphabet in both upper-case and lower-case using Single-Stroke Gothic style.
- Encourage students to use guide lines and focus on uniform height and spacing.
**Conclusion (10 minutes)**:
1. **Review Student Work** (5 minutes)
- Walk around the room to check students' work, giving feedback and corrections as needed.
- Select a few good examples to share with the class, highlighting what was done well.
2. **Recap and Questions** (3 minutes)
- Briefly recap the key points covered: types and styles of lettering, characteristics of good lettering.
- Open the floor for any questions from the students.
3. **Assignment** (2 minutes)
- Assign students a homework task: Write out a short technical note (at least 3 sentences) using both upper-case and lower-case Single-Stroke Gothic lettering. Ensure they use guide lines and keep their work neat.
**Assessment**:
- Students will be assessed on their in-class practice as well as the quality of their homework assignment based on neatness, consistency, and adherence to the techniques taught.
**Closing**:
- Thank the students for their participation.
- Remind them to bring their assignments to the next class for review.
