Understand ratios

Target: Describe a ratio as a comparison of two quantities.

Language target: Use “for every” in a complete sentence.

Likely miss: Students add the two parts or talk about “more than” instead of “for every.”

Ask: Can you say the comparison without adding?

If you see it: Ask the student to point to each quantity before saying the sentence. Cover the total so it cannot become the answer.

Evidence to listen for: The student states both quantities in a for-every sentence without being prompted.

Next: If the language is stable, move to equivalent ratios. If the total keeps appearing, stay with one recipe and rebuild the sentence.

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