Build Challenge

Groups build something from simple materials, then present and justify their creation — generating rich discussion through planning, negotiation, and persuasion.

Procedure

1. Prepare materials: Give each group identical sets of simple supplies (cups, straws, pipe cleaners, uncooked spaghetti, tape, paper, etc.).
2. Brief: Groups have a set time (10–20 min) to build something using only their materials. They decide together what to build.
3. Plan and build: Groups discuss, negotiate roles, and construct their object. Teacher monitors and notes language use.
4. Present: Each group introduces their creation — what it is, how it works, and why it's useful.
5. Q&A: Other groups ask follow-up questions. Class votes on the most creative or useful build.

Variations

• Constrained build: Specify the goal (tallest tower, strongest bridge, most useful invention) to add a competitive element.
• Warm-up: Before building, give groups 2–3 common objects and ask them to brainstorm five unusual uses for each — gets creative thinking going.
• Add a pitch: Groups must "sell" their product to the class, practising persuasive language.

Tips

• Keep material sets identical so the focus stays on language and creativity, not resources.
• Set a visible countdown timer — time pressure drives negotiation and decision-making talk.
• For higher levels, have groups discuss the process afterwards: what went well, what they'd change, who led and why.
