Lesson Plan for Senior Secondary 1 - Technical Drawing - Lettering: Types And Styles Of Lettering

**Lesson Plan: Technical Drawing - Senior Secondary 1** **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. --- **Instructor Notes**: - Be patient with students as they develop this new skill. - Provide positive reinforcement to encourage continued improvement. - Tailor feedback to individual student needs, acknowledging effort and providing constructive critique where necessary.
