Today’s challenge
Compare tabs, slots, tape, fasteners, folds, and reversible connections.
Grade 3 focusPicture routines, modeled tool use, two-option sketches, and short spoken evidence statements.
Grade 5 focusStudent-managed roles, measurable criteria, material budgets, and written design decisions.
Success example · inspiration, not a design to copy
Look closely. What makes this successful?
Tabs, folds, and connectors are neat enough to hold their shape during use.
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 did you notice?
2. What rule, need, or problem matters today?
3. Draw or describe one example.
Evidence check
Show what you learned.
Your teacher will look for: A labeled joint sampler and a short explanation of when each connection works best.
My evidence
