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: Use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond (e.g., x-axis and x-coordinate, y-axis and y-coordinate).
problem_activity: Narrative
The purpose of this activity is for students to learn stage 3 of the Geoblocks center. Students describe solid shapes using their own language. Students provide clues so that their partner can identify the shape out of a set of 4-6 solid shapes. While students may correctly name the solid shapes, it is not expected in this lesson. Students may describe the shapes in many ways. Monitor for students who:
reference a familiar object: “This shape looks like a ball.”
describe attributes or parts of the shape, such as point and circle for a cone.
use the name of the shape: “This shape is a cube.”
use positional words: “This shape is next to the one that looks like a box.”
The purpose of the activity synthesis is to highlight the language students use to describe shapes (MP6).
MLR8 Discussion Supports.
Synthesis: For each response that is shared, invite students to turn to a partner and restate what they heard, using descriptions and gestures.
Advances: Listening, Speaking
Action and Expression: Internalize Executive Functions.
Invite students to plan how they will describe the shape to their partner.
Supports accessibility for: Organization, Conceptual Processing
Required Materials
Materials to Gather
Geoblocks
Solid shapes
Required Preparation
Each group of 2 students needs 4–6 different solid shapes.
Launch
Groups of 2
Give each group of students 4–6 different solid shapes.
“We are going to learn a new way to do the Geoblocks center. It is called Geoblocks, Describe and Find.”
“Put the solid shapes in the middle, between you and your partner.”
30 seconds: partner work time
Activity
“Think of a shape but don’t tell your partner. Describe one of the shapes to your partner. Your partner’s job is to guess which shape you are describing. Once your partner figures out which shape you are describing, switch roles.”
7 minutes: partner work time
Monitor for students who describe the shapes in the ways described in the activity narrative.
Advancing Student Thinking
If students guess a shape that is not being described, consider asking:
“What clues did your partner give you?”
If needed, consider prompting students to eliminate some of the shapes. For example, ask “Your partner said that the shape has a round part. Are there any shapes that do not have round parts?”
Activity Synthesis
Invite previously identified students to share.
“Which clues did your partner give that were helpful to you?” (My partner said their shape was tall and had a circle on the top and bottom.)
