Factors that shape designs

Examine factors that influence the design of products, services and environments to meet community needs — sustainability (materials, energy, waste), cost, safety, function and appearance — and explain how designers prioritise competing factors

Lesson

Set out your lesson

“Factors that shape designs means practising the idea at the table with real materials and one clear check. We will demo once, then your child tries.”

Bring to the table

  • Picture or object cards for Factors that shape designs
  • Paper and a pencil
Extra for the adult

Worked example. Adult shows one clear example for Factors that shape designs, then the child tries a matching example with a reason. Larger handwriting would not change the idea.

Optional challenge. For Factors that shape designs, add one harder example after success.

What to notice. Keep one parent note: examples tried; reasons; support used. This session samples Factors that shape designs, not mastery.

Selected Default Gakuva

Factors that shape designs means practising the idea at the table with real materials and one clear check. We will demo once, then your child tries.

Materials: cards/paper for Factors that shape designs. Adult models one concrete example. Child completes three matches or retells with reasons. Done: three correct responses with a spoken reason each. Stop after those three; keep optional challenge for another day.

Check understanding

  • Identify the factors a designer considered in a familiar product or place (e.g. a playground: safety, cost, shade, accessibility)
  • Explain how sustainability affected a real design (e.g. recycled-plastic benches, solar lights in a park, a reusable coffee cup)
  • Rank competing factors (e.g. function, safety, cost, users' needs) for a design brief, explain the priority order and the trade-off it creates (e.g. a more sustainable choice might cost more)
“Can your child explain why a park bench might be made from recycled plastic — and what else designers had to think about, like cost and safety?”
