Write algebraic expressions

Target: Translate a phrase into an expression.

Language target: Match “more than” and “twice” to operations.

Likely miss: Students write the operations in the order the words appear, so “3 more than twice n” becomes 3 + 2 × n without the intended structure, or 3n + 2.

Ask: What is doubled, and what is added after that?

If you see it: Ask which quantity is doubled and which amount is added after that.

Evidence to listen for: The expression matches the phrase “twice, then more.”

Next: Keep the phrase and change only the numbers.

Observable student moves: names both quantities, uses the represented relationship, and revises after feedback. This companion is not a score.
