Keywords

• Board Practice – The correct way of handling drawing tools and materials on the drawing board.
• Title Block – A section on the drawing sheet that contains information such as the title, date, and name.
• Border Lines – The lines that frame a drawing sheet.
• Parallel Lines – Lines that run side by side and never meet.
• Vertical Lines – Straight lines that run from top to bottom.

Set Induction (Entry Behavior)

• The teacher displays a properly set-up drawing sheet and an incorrectly set-up one.
• The teacher asks students to describe what they notice about both sheets.

Learning Resources and Materials

• Drawing board
• Drawing paper
• T-square and set squares
• Drawing pencils (HB, 2H)
• Compass and dividers
• Eraser and masking tape
• Ruler and protractor

Building Background/Connection to Prior Knowledge

Students have previously learned about drawing instruments and how to care for them. This lesson will focus on how to use them properly on a drawing board.

Embedded Core Skills

• Creativity – Designing neat and accurate drawings.
• Critical Thinking – Applying precision in using drawing instruments.
• Collaboration – Working with classmates to improve drawing techniques.

Lesson Content

1. Setting the Drawing Paper on the Drawing Board

To correctly attach a drawing paper to the board:

1. Place the drawing paper at the center of the board.
2. Align the paper with the edges of the board using a T-square.
3. Secure the paper with masking tape or clips at all four corners.
4. Ensure the paper is smooth and flat to avoid errors while drawing.

2. Sharpening a Pencil to a Conical Point and Knife Edge

• Conical Point:
  • Use a sharpener or sandpaper to create a smooth, rounded tip.
  • Suitable for general sketching and freehand drawing.
• Knife Edge:
  • Use a sharp knife or blade to carve one side of the pencil to a sharp edge.
  • Suitable for technical and precise drawings.

3. Using Drawing Instruments to Draw Basic Lines
