Intro to Trigonometry

We made this page using small squares of transparency film. Again, this manipulative shows this concept so well that my students were so shocked that this was trig, because "trig is hard! I can do this!!!" 

You're welcome, kid. 


  1. I LOVE this! How did you get the transparency film to stay in the little windows? I'm teaching an entire semester of trig next year, and I think this would make an awesome addition to our notebooks!

  2. Thanks! Some students used tape (the one in the picture is taped), and others stapled the transparency sheet in. That seemed to work just fine!

  3. Love this and stealing it! What kind of markers did you use?
