Do Now · 5 min
Set your bridge on the front bench with a card showing your team name. Walk around the room for 2 minutes — just LOOK, don't touch. Notice which bridges impress you.
I Do · ~10 min Teacher demonstration
Teacher models a peer review using the rubric.
Project the rubric. Pick a bridge. Walk through:
- Build quality — joints clean? Symmetry? Triangulation complete?
- Match to design — does it look like their L08 drawing?
- Finish — neat?
Write: "One thing your bridge does well: ___. One improvement I'd suggest: ___. Why: ___."
We Do · ~15 min Guided practice
Swap teams with a partner pair. You have 10 minutes to:
- Inspect (don't touch) their bridge
- Fill in the peer review form (hand-written or typed)
- Hand back with kindness
You Do · ~35 min Independent pair work
One-improvement lap (30 min).
- Read the feedback you received.
- With your partner, pick ONE improvement to make this lesson. Just one.
- Write in your journal: "Improvement: ___. Why we chose it: ___ (2 sentences)."
- Do the improvement. Photograph before and after.
