Write About the Math
The school cafeteria is planning a new lunch menu. They want to offer 3 main dishes for every 2 side dishes. If they have 10 side dishes, the cafeteria manager needs to figure out how many main dishes to prepare?
Say your answer to a partner first. Then write it, using at least two of these words:
Model: The recipe uses 3 cups of apple juice for every 2 cups of sparkling water. — A strong answer names that apple juice and sparkling water are being compared and states the relationship as 3 to 2 (or 'for every 3 apple juice, 2 sparkling water'), not just that there is more apple juice.
