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, determine whether the following problem or activity can enable students to understand the concepts or skills in the provided description.

Estimate and Measure Stage 2 Recording Sheet

Narrative
Students choose an object and a unit (inches, feet, centimeters) to measure it with. They estimate the length of the object and then measure to see the actual length to the nearest whole unit.
Additional Information
Gather or identify objects of various lengths (pencils, markers, books, glue, scissors, shoes, tape dispensers, sides of desk, length of bulletin board).
