This is a game I created to get students engaged with the facts about trigonometric functions.
The cards include:
The names of all 6 trigonometric functions, the phrases “is even” and “is odd”, the domains and ranges of all six functions and the phrases “the domain of” and “the range of”, the constants 1, pi, and 2pi, the phrases “is the set of”, “equals”, “and”, “plus”, “minus”, “equals”, “the quotient of”, “the square of”, “the reciprocal of”, and “the period of”.

Two sample sentences.
This means it is easy to play with all the cards, or only the cards that are about a certain subtopic, like domain and range, or constructing identities.
When I played with my own class I divided the class into groups of about 4. I shuffled the cards and put them in 12 roughly equal face up stacks under the document camera. Each group started with 7 cards.
On each group’s turn, someone came up to the desk and chose four cards from any combinations of stacks. They then had the option to turn in a sentence, but if they couldn't make one according to the sentence rules, they had to discard a card.
We played with books open to a summary of the relevant facts.
Sentences had to have at least 3 cards and each clause needed to have a trigonometry fact—that is, no sentences like “pi plus pi equals 2pi.”
I scored them by subtracting 2 from the number of cards and squaring the result—so a 5 card sentence would be worth 9 points, but a 6 card sentence would be worth 16 points.
Of course you can come up with other ways to use them according to your own creativity.
