Example 1:
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?


Description: 
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.

Example 2:
Problem/activity:
For each pair of numbers, determine if the values are equivalent. Explain your reasoning for each one.
a.
$$-0.25$$
and
$$\frac{1}{-4}$$
b.
$$-\left ( \frac{1}{4} \right )$$
and
$$\frac{-1}{-4}$$
c.
$$\frac{-1}{4}$$
and
$$-\frac{1}{4}$$


Description: 
Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.

Answer: 
No. The expressions shown in this problem do not involve multiplying fractions with other fractions, nor whole numbers with fractions.

Problem 2
Kim has a small container and a large container as shown.
[IMG]
It takes 16 of the small containers to fill the large container. Three small containers leave 1.95 gallons of space in the big container.
What is the size of each of the two containers?


Description: 
Prove that, given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solutions.

Answer: 
No. Completing neither of these problems requires replacing one equation by the sum of that equation and a multiple of the other equation.

standard_description: Compose simple shapes to form larger shapes. For example, “Can you join these two triangles with full sides touching to make a rectangle?”
problem_activity: Narrative
The purpose of this activity is for students to put together pattern blocks to form larger shapes in more than one way. Students create hexagons using different combinations of pattern blocks. In the synthesis, students discuss whether the same pattern blocks in different orientations should be considered as different ways to make a hexagon (MP3). There is no one correct answer to the question. The goal is for students to notice and discuss that the same pattern blocks are arranged in different orientations.
MLR8 Discussion Supports.
To support the transfer of new vocabulary to long-term memory, invite students to chorally repeat these words in unison 1–2 times: more, fewer, the same as.
Advances: Listening, Speaking
Required Materials
Materials to Gather
Pattern blocks
Launch
Groups of 2
Give each group of students pattern blocks.
“Work with your partner to find many different ways to make hexagons with pattern blocks. Tell your partner about the shapes that you use each time using ‘more’, ‘fewer’, or ‘the same number’.”

Advancing Student Thinking
If students find one or two ways to fill in the hexagon pattern block puzzle:
“Tell me more about which pattern blocks you used to make the hexagon.”
“Can you use these green triangle pattern blocks to make this red trapezoid pattern block? How can that help you find another way to fill in the hexagon?”
Activity Synthesis
Invite students to share different ways they made a hexagon.
As students share, say “Tell your partner about the shapes that they used using ‘more’, ‘fewer’, or ‘the same number’.”
Display all of the ways to make a hexagon that students have shared.
“Are there any other ways to make a hexagon with pattern blocks?”
Display 2 hexagons created with 2 blue rhombus pattern blocks and 2 green triangle pattern blocks in different orientations:

[IMG]
“Han and Clare shared these ways to make a hexagon with pattern blocks. Are these the same way to make a hexagon or a different way? Why do you think that?” (They are the same because they used the same pattern blocks but put them in different spots. It looks like they flipped it. They are different because the pattern blocks are in different places, so they look different.)
