This is a simulation, not a quiz. You answer by trying things and watching what happens.
Our question
When is canceling a term legitimate, and when does it change the value?
Getting the simulation ready…
- 1Build or change something
- 2Say what will happen, then run it
- 3Finish: say what you found
What counts as evidence- The bar before and after canceling.
- A case where the shaded edge moves.
- A conclusion must address the Fraction Forge question.
