Students will practice simplifying trigonometric expressions in terms of a single trigonometric function (or numerical value) with this “Triples” Activity. There are 24 total cards. Once matched, there will be 8 sets of 3 cards that simplify to the same value.
Simplification requires the use of the Reciprocal Identities, Quotient Identities, Pythagorean Identities, and Double-Angle Identities. Students must also be able to factor, combine fractions, and distribute. There is also an alternative version without Double-Angle Identities.
I recommend that students work in groups of 3-4 on this activity. 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 is included to ensure the correct cards are matched.
