Model
Quantities and representation
Run the baseline and one changed case. Keep the named controls fixed.
- Represent
- Fraction Forge table, visual model, and symbolic rule
- Invariant to test
- Make equal shares and explain how the whole is divided without introducing symbolic procedures too early.
- Proof limit
- A single valid case cannot establish a universal claim.
Evidence
Computed comparison
Commit a testable model and run the investigation to generate evidence.
