My honors precalculus students saw the slope hexaflexagons my geometry students were using and asked when they would get something like that. I promised when we reached our trig unit, I’d whip something up. Below is the result as well as a video explaining how to assemble a hexaflexagon. My hope is that my students become well versed with their reference angles and don’t need to write out a complete unit circle when answering questions this semester.

Here’s a link to download the instructions and a pair of trig hexaflexagons.
