Unit Circle Triples Activity
With this triples matching activity, students will practice fluency in identifying exact trigonometric function values for angles found on the unit circle. Functions include sine, cosine, tangent, cosecant, secant, and cotangent. Cards 1-18 are angles given in degrees. Cards 19-36 are angles given in radians.
Students find the exact value for each of the 36 cards, then look for the matching "triples". There will be 12 sets of three cards, each having the same answer. Students can work on their own or with a partner to match the cards. They can show their work directly on the back of the card, or on a separate sheet of paper if you prefer. Once they are finished, I have my students staple their "triples" together and place in a zip-lock bag.
An answer key to use to ensure the correct cards and matched.
