Lesson Plan

• Describe what vector graphics are and why they are resolution‑independent.
• Explain the mathematical basis of quadratic and cubic Bezier curves.
• Apply the Pen/Bezier tool to create and edit anchor points and control handles.
• Construct a closed shape by joining multiple Bezier segments.
• Evaluate appropriate vector file formats for different output contexts.

• Computer with vector‑editing software (Inkscape or Adobe Illustrator)
• Projector or interactive whiteboard
• Sample SVG files and handout of Bezier equations
• Worksheets with step‑by‑step logo task
• Mouse or graphics tablet

Begin with a rapid poll asking students to name everyday images that stay sharp when enlarged. Connect this to their prior work on raster graphics and set the success criteria: “By the end of the lesson I can create a smooth, scalable shape using Bezier curves and choose the right file format for its use.”

1. Do‑Now (5’) – Quick quiz on vector vs raster concepts to activate prior knowledge.
2. Mini‑lecture (10’) – Explain quadratic and cubic Bezier equations with visual diagrams.
3. Demonstration (12’) – Live modelling of a simple logo using the Pen tool; show anchor placement and handle adjustment.
4. Guided practice (15’) – Students follow a worksheet to recreate the logo while the teacher circulates.
5. Extension activity (8’) – Students modify the shape to create a rounded rectangle or star using multiple Bezier segments.
6. Check for understanding (5’) – Exit‑ticket: write one advantage of using a cubic Bezier over a quadratic.

Recap the key steps of building and editing Bezier paths and the importance of choosing the correct vector format. Collect the exit‑ticket responses and assign homework: each student creates a personal icon, saves it as an SVG, and prepares a brief note on its intended use.
