Rewrite, then evaluate
Target: Keep every term while finding the value of an expression.
Language target: Separate “simplify” from “find the value.”
Likely miss: Students simplify and evaluate as if they were the same step.
Ask: Is the variable still in your expression, or did you already evaluate?
If you see it: Ask whether the variable should still be visible when the work stops.
Evidence to listen for: The student can both rewrite and then evaluate a new value.
Next: Separate the two questions on the page if they collapse into one.
Observable student moves: names both quantities, uses the represented relationship, and revises after feedback. This companion is not a score.
