3D MODELING • TEACHER GUIDE
Dream Room: Five-Day Capstone
Students plan from real references, convert measurements, build at a consistent scale, test the model with another person, revise, and submit evidence from Tinkercad.
Five-day flow
- Day 1: Plan. Choose a room, collect five reference items, and record real dimensions.
- Day 2: Scale. Work one conversion row together. Students convert the room and three items by hand before using the calculator.
- Day 3: Build the room shell. Floor, walls, door, window, and the first large object.
- Day 4: Build and test. Add at least three recognizable items. A partner checks scale, navigation space, and whether the room reads as intended.
- Day 5: Revise and submit. Fix one issue from feedback, inspect print-readiness, export the PNG, and explain the revision in submission comments.
Teach scale before the worksheet
Use the scale deck for the whole-group mini-lesson. The arithmetic is not the point by itself. Students need to understand that every object must use the same scale or the room stops making visual sense.
Leave-up screen: use the deck's final Convert + Build slide while students work.
