Concept/skill: 
Recognize and represent proportional relationships between quantities.

Problem/activity:
You’re mixing ingredients for cookies. The recipe says to combine 6 tablespoons, or ¾ stick, of butter with 1 cup of sugar. You accidentally mix in a whole stick of butter (8 tablespoons) with the cup of sugar. How can you fix this?


Answer: 
No. Usually problems that teach recognizing and representing proportional relationships between quantities involve deciding whether two quantities are in a proportional relationship or identifying the constant of proportionality, and then representing proportional relationships by equations or explaining proportional relationship using coordinate graphs.

Now, determine whether the following problem or activity can enable students to understand the concepts or skills in the provided description.

standard_description: Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding. (This standard is limited to problems posed with whole numbers and having whole number answers; students should know how to perform operations in the conventional order when there are no parentheses to specify a particular order (Order of Operations).)
problem_activity: Narrative
The purpose of this activity is for students to write a question that could be answered by given mathematical work and that would make sense in the given situation. When students interpret given student work in terms of the supplied information and decide what question the work might answer, they identify important quantities and their relationships in context (MP4).
MLR8 Discussion Supports.
Prior to solving the problem, invite students to make sense of the situation and take turns sharing their understanding with their partner. Listen for and clarify any questions about the context.

Groups of 2
“Clare and Tyler took a break at the lemonade stand. Here’s what it might look like.”
Display the image.
“What do you notice? What do you wonder?” (Students may notice: The stand is close to the carnival. There are lemons hanging in baskets. Students may wonder: How much lemonade do they make each day? What size can you buy? How much does the lemonade cost?)
1 minute: quiet think time
Share and record responses.
Activity
Read the information about the lemonade stand as a class.
“What mathematical questions could we ask about this situation?”
1–2 minutes: partner discussion
Share and record responses.
“Now, look at the mathematical work in each problem. Work with your partner to write a question that could be answered by that work.”
5–7 minutes: partner work time
Monitor for groups that accurately write questions that the work could represent.
Student Facing
A lemonade stand at the fair makes 132 liters of lemonade a day. When Clare and Tyler stopped by the stand, there were 90 liters left.
At the end of the day, there were 56 liters of lemonade left, which the vendor put on sale in 4-liter jugs.

Advancing Student Thinking
If students don’t write a question that could be solved with the given work, consider asking:
“What numbers from the work do you see in the information about the lemonade stand?”
“What would the work represent in the lemonade stand situation? What question would lead up to this work?”
Activity Synthesis
For each problem, invite a group to read the question they wrote.
Ask the class:
“How does their question make sense with this mathematical work and what we know about the situation?”
Consider asking:
“What did you like about writing the questions to match the mathematical work?”
“What was challenging about writing the questions to match the mathematical work?”
