This is a simulation, not a quiz. You answer by trying things and watching what happens.
Our question
What can you investigate in Algebra Lab to represent an unknown quantity with a concrete box and preserve equality through matching moves?
Getting the simulation ready…
- 1Build or change something
- 2Say what will happen, then run it
- 3Finish: say what you found
What counts as evidence- Build a claim and connect it to one result from your trial.
- Choose how you would check the idea in one new example.
- Three counters in the box make both sides total five.
- First Balance: predicted what should change before this action: Read the equation on the balance scale (x + 3 = 7).
