Writing Trig Ratios Domino Set
Students practice identifying trig ratios in a game format. Set includes 4 different sets of dominoes: 8 Dominoes, 12 Dominoes, 16 Dominoes and 24 Dominoes. Each set has a triangle with side measures and the trig ratio(either sine, cosine or tangent) sought on half the cards with the other half has a ratio. The smaller sets are great for pairs or even a student who likes to work alone. The larger sets are good for groups of 3 or 4.

Dominoes are cut apart, placed face down and students draw all dominoes equally. Student with "start" places the first domino and then student with the diagram/trig ratio in their hand plays the next. This continues until one student is out of dominoes and is declared the winner. I usually give 5 points per domino left in other students hands and keep a running tally.

Students love playing games in the classroom and this set will give them the opportunity to practice identifying their trig ratios. For students who struggle, have them practice checking the solutions into the system to determine the answer.
