Students play a matching game where they have to find three cards that make a trig equation from the first quadrant.
One card is the trig function (sine, cosine, tangent), another is the angle (30, 45, 60 or radian equivalents), and the last is the trig value. For example, a trio would look like Sin 30 = 1/2.
Once three cards are taken from the board, they are replaced and play continues. Students must also write down their trig equation.
This is a really fun way to get kids to memorize t
