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: 
Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.

Answer: 
Yes. This problem solves a real-world problem involving mixing ingredients for cookies. A student doing this problem would need to reason about equivalent ratios of butter amounts to sugar amounts.

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 1
The table below contains single equations in a single variable, single equations in two variables, and pairs of simultaneous equations in two variables. Check the appropriate box to show whether there is no solution, exactly 1 solution, or if there is an infinite number of solutions.

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: 
Analyze and solve pairs of simultaneous linear equations.

Answer: 
Yes. The last three rows of the table in the first problem involves solving pairs of simultaneous linear equations. The second word problem can also be represented as two simultaneous linear equations.

problem_activity: Narrative
The purpose of this activity is to introduce stage 2 of the Connecting Cubes center. Students use connecting cubes to make objects pictured on cards. As they work, observe whether students match the connecting cubes to the image or count the number of connecting cubes in the image to create their own object (MP6).
Required Materials
Materials to Gather
Connecting cubes
Materials to Copy

Required Preparation
Create a set of cards from the blackline master for each group of 2.
Launch
Groups of 2
“We are going to look at a new center that you can choose during center choice time.”
Display the student book.
“How could you use connecting cubes with this picture?” (We can make things with our connecting cubes that look like the picture in the book.)
30 seconds: quiet think time
1 minute: partner discussion
Share responses.
Activity
Give each group of students connecting cubes and a set of cards.
Display the student page.
“Use your connecting cubes to build this object.”
