(Recently Revised!) This is a game I use with my students to review trig ratios. The game is played like around the world... two students go against each other, the first to say (or write) the answer win and move on to challenge the next student. There are 50 slides, plenty to engage a whole class for 50 minutes. The revised version is bold, clear, and easy to read on a white background. There are also several types of right triangles in various orientations to keep things exciting. Enjoy! And I almost forgot... answers are included!
