I Have... Who has? This activity is designed to be a quick review activity of the 6 trig values for angles on the unit circle. There are 18 different slides, which connect together in a loop, so it doesn't matter which card is the first card. I have about 36 students in each class, so I print out two sets on different colored paper, split the students into two teams, and they race to complete their loop first.
*Tip* To save paper, do not print all the slides separately. Select the option to print 6 slides on a paper and select slides 3-20, which uses only 3 pieces of paper per set. Also, if you use card stock, the set is more durable.
