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: Understand division as an unknown-factor problem. For example, find 32 ÷ 8 by finding the number that makes 32 when multiplied by 8.
problem_activity: Narrative
The purpose of this Number Talk is to elicit strategies and understandings students have for dividing within 100 and to help students develop fluency.
When students use known multiplication and division facts to divide larger numbers, they look for and make use of structure (MP7).

Activity Synthesis
“How did you use division facts that you already know to find some of the other quotients?” (I knew that
\(60\div3\)
would be double the answer of
\(30\div3\)
. Once I knew
\(60\div3\)
, I was able to find
\(63\div3\)
by adding another group of 3 and
\(54\div3\)
by taking groups of 3 away.)
