This is a simulation, not a quiz. You answer by trying things and watching what happens.
Our question
What controlled comparison will help you represent a story situation with objects, actions, and an equation appropriate to the grade?
Getting the simulation ready…
1Build or change something
2Say what will happen, then run it
3Finish: say what you found
What counts as evidence
Select the measured comparison that directly addresses the prediction.
Name the changed condition, cite one result, and connect it to this goal: Represent a story situation with objects, actions, and an equation appropriate to the grade.
Your representations, quantified comparison, justification, and counterexample become inspectable mathematical evidence.
Read and Solve: predicted what should change before this action: Read the word problem.
