Today’s challenge
Observe slicing and printer workflow; document predictions while adults operate machines.
Grade 3 focusBasic solids and holes, align/group, large features, guided file naming, and teacher slicing.
Grade 5 focusRuler-based dimensions, tolerance tests, fit systems, orientation choices, and material/print-time limits.
Success example · inspiration, not a design to copy
Look closely. What makes this successful?
The print is oriented carefully and students compare first-layer results with predictions.
What to do
- Understand. Read the challenge. Circle the important need, rule, or safety limit.
- Plan. Use the thinking spaces below before you begin making.
- Make. Build, model, code, practice, or investigate carefully with your team.
- Check. Use evidence—not guesses—to decide what worked.
- Improve or explain. Make one useful change or share your strongest conclusion.
Engineer’s thinking
1. Draw and label your plan before building.
2. List the materials, parts, or digital tools you will use.
3. Record one change you make while building.
Evidence check
Show what you learned.
Your teacher will look for: A print-job ticket with orientation, time, material, and first-layer predictions.
