Example:
Concept/skill: 
Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles.

Problem/activity:
Find the general solution for:
$${\mathrm{cos}\left({\pi\over2}+x\right)=\mathrm{tan}{\pi\over4}}$$


Answer: 
No. This problem does not directly teach how side ratios in right triangles lead to definitions of trigonometric ratios. Instead, it involves solving a trigonometric function.

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

standard_description: Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
problem_activity: Narrative
The purpose of this activity is for students to put numbers 1–20 in order.
MLR8 Discussion Supports.
Invite each group to chorally read numbers 1–20 in order once the group agrees on the order. Listen for and clarify questions.
Advances: Speaking, Conversing
Required Materials
Materials to Copy
Number Cards 1-20
Required Preparation
Create a set of cards from the blackline master for each group of 4.
Launch
Groups of 4
Give each group of students a set of number cards, not in sequence.
Activity
“Work with your group to put the numbers in order from 1 to 20.”
3 minutes: small-group work time
“Once your group agrees that the numbers are in the correct order, write the numbers in order from 1 to 20.”
3 minutes: independent work time
Student Facing
Write the numbers in order.

Activity Synthesis
“How did you decide the order of the numbers?”
Display numbers 1–12 in order.
“Clare is putting the numbers in order. What would you say to her to help her find the number that comes next?” (Look for 13 because it comes after 12. Look for the number that has a 3 because the last number has a 2.)
