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


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.

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, does the problem or activity shown below enable students to learn the full intent of the following concept or skill?

standard_description: Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), ...
problem_activity: Narrative
The purpose of this activity is for students to find the volume of figures composed of two non-overlapping right rectangular prisms by adding the volumes of the non-overlapping parts. There are different ways to decompose the figures. Monitor for students who break the figures apart differently and find the same total volume. To reinforce earlier work with cubic units of measure, ask students for the unit of measure in their response if they state the volume as only a number (MP2). If students finish early, give them isometric grid paper to draw a figure composed of two rectangular prisms for their partner to find the volume.

Isometric Dot Paper Standard
Launch
Groups of 2
Display the image from the student workbook with the missing side lengths.
“How can we find the missing side lengths?”
1 minute: quiet think time
2 minutes: partner discussion
Share and record responses on the image of the figure.  (We can subtract 5 from 7 in both cases.)
Activity
“Now, each partner will find the volume of one of the figures and then switch papers. Your job is to then find the volume using a different decomposition strategy than your partner.”
If there is time, the groups of 2 can make groups of 4 and share responses and strategies.
10 minutes: independent work time with partner discussion
Give students access to isometric dot paper to draw the figures if they finish early.

Advancing Student Thinking
If students do not find the correct volume of the figure, ask, “Where do you see rectangular prisms in this figure?”
Activity Synthesis
Display: Figure 2
“How did you break up this shape to find the volume?” (I cut off the overhanging piece vertically to make two rectangular prisms. I cut off the bottom piece that the shape is resting on, horizontally.)
“How did you find the side lengths of the rectangular prisms?” (Some of the lengths are provided, and I found the others by subtracting.)
“Did you get the same volume when you broke up the figure differently? Why?” (Yes. The calculations were different but they both tell me how many cubic inches it takes to fill the shape.)
