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 problem or activity shown below enable students to learn the full intent of the following concept or skill?

standard_description: Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.
problem_activity: Narrative
The purpose of this activity is for students to order numbers. Students estimate the location and label numbers on a number line, and then write them in order from least to greatest or greatest to least. For the third set of numbers, students may order the numbers using any method that makes sense to them. Students reflect on how the number line can help us organize numbers (MP5). Throughout the activity, monitor for the way students explain their reasoning based on place value and the relative position of numbers on the number line.
Representation: Access for Perception.
Use index cards, clothespins, and string to demonstrate the number line. Give students the numbers on the index cards and have them physically act it out by finding their place on the number line.

Activity
“Now you will have a chance to order numbers.”
“Sometimes you will put them in order from least to greatest, and sometimes it will be from greatest to least.”
10 minutes: independent work time
“Compare with a partner. Explain your thinking.”
5 minutes: partner discussion
Monitor for students who order the last set of numbers by:
explaining their reasoning using precise place value language
placing each number on the number line before ordering the numbers

Estimate the location of 839, 765, 788, 815, and 719 on the number line.
Mark each number with a point. Label the point with the number it represents.

Advancing Student Thinking
If students locate the numbers on the number line, but reverse the order given in the problem, consider asking:
“How did you decide the order of your numbers?”
“Does your list show the numbers in order from least to greatest or greatest to least?”
Activity Synthesis
Invite previously identified students to share their reasoning.
“How are the numbers you labeled on the number line the same as the list of numbers you wrote? How are they different?” (For least to greatest, its the same. The difference is the number line shows the distance between each number, but the list of numbers shows them right next to each other.)
