Example:
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
$$-\frac{1}{4}$$


Concept/skill: 
Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.

Answer: 
Yes. This problem involves understanding fractions and division to divide rational numbers, such as 1, -4, 4, and -1. This problem also involves an understanding of multiplication: if p and q are integers, then -(p/q) = (-p)/q = p/(-q).

Now, assess whether the following problem or activity is 'aligned' with the given Common Core standard in Mathematics.

standard_description: Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.
problem_activity: Narrative
The purpose of this activity is for students to create a poster of their story problem so that others can solve it. Students use these posters in the next activity, in which they solve, and write equations for other students’ story problems. They notice connections between the equation and the written problem and create a poster that communicates their work.
Alternatively, to make this task more challenging, students can rewrite their stories as missing addend story problems.
Required Materials
Materials to Gather
Tools for creating a visual display
Launch
Groups of 2
Give each group tools for creating a visual display.
“Now we’re going to use your story problems from the last activity to make posters so we can show our thinking and challenge each other.”
Activity
“Choose one of the story problems you and your partner wrote. Create a poster with your story problem. Your classmates will solve it in the next activity. So make sure to not include the answer.”
5 minutes: partner work time.
“Take turns sharing your poster with another pair at your table.”
“The pair listening should tell the presenters if their poster is clear and organized.”
5 minutes: group work time.
If needed, give students an opportunity to revise their posters.

Activity Synthesis
“What were some things you changed to make your poster clear and organized for the gallery walk?” (We wrote the story problem bigger. We added a picture to go with my story.)
