Our Trig BFF: The Unit Circle - I'm not sure my students just realized how familiar they were going to become with the unit circle!
In retrospect, I would have also given students laminated unit circles/formula sheets to keep in a pocket in the back of their notebooks.
Using our unit circles, we filled out this table of trig ratios for the first quadrant.
Notes on how to find trig ratios from the unit circle:
Then, notes on how to generalize trig ratios for each quadrant. My trig teacher taught us "All students take calculus." Since my school doesn't offer calculus, I introduced it as "All students take classes." However, many of my students made up their own way to memorize the signs of trig functions in each quadrant.

We finished off the unit with a trig ratio puzzle.
