Lesson Plan
Grade: Date: 17/01/2026
Subject: Design and Technology
Lesson Topic: Processes: cutting, shaping, joining, finishing
Learning Objective/s:
  • Describe key properties of resistant materials and how they influence process selection.
  • Compare cutting, shaping, joining, and finishing methods and identify appropriate applications.
  • Apply safety procedures when operating workshop tools and equipment.
  • Analyse a simple design problem to select suitable processes and materials.
  • Evaluate the quality of a finished product using appropriate criteria.
Materials Needed:
  • Projector and screen
  • Whiteboard and markers
  • Sample material specimens (wood, acrylic, metal sheet)
  • Cutting tool examples (hand saw, laser‑cutting video)
  • Bending press or manual bender (demo)
  • Welding/fastening demonstration materials (or video)
  • Safety goggles, gloves, hearing protection
  • Worksheets with process comparison tables
Introduction:

Begin with a quick poll: “What everyday objects have you noticed being cut, shaped, joined, or finished?” Connect this to prior knowledge of material properties and set the success criteria – students will be able to match processes to material characteristics and demonstrate safe workshop practice.

Lesson Structure:
  1. Do‑now (5’) – Students list processes they have observed in common products on sticky notes.
  2. Mini‑lecture (10’) – Overview of material properties and how they guide the choice of cutting, shaping, joining, and finishing.
  3. Cutting demonstration (15’) – Show short videos of saw, laser, and water‑jet cutting; discuss advantages, disadvantages, and safety.
  4. Hands‑on activity (20’) – In groups, examine sample specimens and complete a worksheet matching each specimen to the most suitable process.
  5. Shaping & joining demo (10’) – Live demonstration of bending a sheet metal piece and a mechanical fastening example, highlighting PPE.
  6. Finishing discussion (10’) – Review polishing, painting, and coating; work through a simple paint‑thickness calculation.
  7. Check for understanding (5’) – Quick exit‑ticket quiz on process‑property relationships.
Conclusion:

Recap the four main process categories and the key safety rules reinforced during the demos. Students complete an exit ticket summarising which process they would choose for a given design brief. Assign homework: research a real‑world product and create a short report outlining the cutting, shaping, joining, and finishing steps used.
