I found
this style of foldable browsing around one day and just KNEW it had to be a part of my class somehow! It is the coolest thing since sliced bread when it comes to foldables.....and what's even better is that the
students think so too!!!
This is my adaptation of the foldable for trig functions. On the outside you can see the basic SohCahToa with triangles where you set up the ratios (including it related back to the unit circle in the coordinate plane). Then there's a section where you solve for missing sides in triangles...both where the variable is up high (multiply) and down (divide). The last section is where you would solve for angles. In the secret section (cue the shocked faces of your students) is where they look at the graphs of sine and cosine (tangent wasn't in our AFM standards, but I'm sure you could find a way to fit in if needed).
This would also be a good spot to refer back to
function transformations and discuss how it all relates.
