Cardboard Slot Tests
Laser Cutting · 2 xTool laser cutters
Today’s challenge
Prototype cross-slots and tabs before any machine cutting.
Grade 3 focusTrace and simplify bold shapes, use teacher templates, and test one slot size.
Grade 5 focusCreate measured vector files, compare kerf/slot tests, nest parts, and justify assembly choices.
Success example · inspiration, not a design to copy
Look closely. What makes this successful?
The slot fits snugly enough to hold but does not require forcing the pieces.
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. What will you keep the same?
2. What one thing will you test or change?
3. Record the result with a number, tally, or clear observation.
4. What should you improve next?
Evidence check
Show what you learned.
Your teacher will look for: A slot-fit table and a justified width choice.
