Trig Problem 2. (Standard: Law of Sines, Law of Cosines and applications)
Figure out some of the missing information in the diagram.
The pictures were made in GeoGebra, which I highly recommend for mathematical image creation, as well as more active uses.
Geometry Problem 1. (Standard Lines: parallel, perpendicular, properties of angles)
Find more angles.
|Geometry Problem 1|
Similarities: visual, finding connections, geometry, students have previously done and been assessed on similar problems.
|Have to love easy-to-draw memes.|
It was fascinating to read their work, and I wish we had more class time to look at the results. It felt like direct confirmation of the Van Hiele levels, and convicted me that as much time as we devoted to trigonometry, I need to find more ways to increase their experience. While I thought the circle diagram was more subtle, I didn't realize the great difference in how students would see it. Only one student realized CD must be 6 units, which is the entry to me for many of the possible values that can be determined.
