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?


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

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, does the following problem or activity enable students to learn the full intent of the following concept or skill?

standard_description: Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
problem_activity: Narrative
The purpose of this activity is for students to make sense of an Add To, Change Unknown story problem and identify the answer within an equation. Students are presented with a drawn representation and an equation to interpret. Students consider what each number in the equation means in relation to the story problem and drawn representation (MP2). They determine that the written equation is incorrect, and explain why using their own thinking. When students practice explaining their thinking, they begin to develop and refine their mathematical communication skills, and attend to precision (MP6). Students identify that even though Mai's equation has the correct numbers she identified the wrong number as the solution to the problem (MP3).
Students keep their books closed for the launch of the activity, as the teacher displays and reads the problem.
Action and Expression: Internalize Executive Functions.
Invite students to plan a method, including the tools they will use, for solving the rest of the story problems. If time allows, invite students to share their plan with a partner before they begin.

Share and record answers.
Activity
"Now we will get more information and see how Lin solved the problem."
Read the problem aloud.
"Look at Lin's drawing and her equation. Think about how she solved the problem."

Student Facing
Andre checked out some books from the library.
Mai gives him more books.
Now he has 9 books.
What do you notice?
What do you wonder?
Andre checked out 3 books from the library.
Mai gives him some more books.
Now he has 9 books.
How many books did Mai give him?
Lin made this drawing.
[IMG]
She wrote the equation
\(3 + 6 = \boxed{9}\)
Is her equation correct?
Show your thinking using drawings, number, or words.

Activity Synthesis
“How does Lin’s drawing show the story problem?” (She shows the three books Andre starts with, and the six books she needs to get to nine.)
"Does Lin's equation match the story? Why or why not?" (No. The answer to the problem is how many books Mai gives Andre. That answer is 6, so the equation should be
\(3 + \boxed{6} = 9\)
.)
If needed ask, “How does this equation match the story problem?” (Andre has three books. Mai gives him six, which is the answer, so that he has nine total.)
