If you want students to know their radians, sines, and cosines quickly, then this is the game for you and your students--especially if they are a competitive group like mine.

Students will be given a radian, point, quadrant signs, or an axis label and they have to click on the blue button quickly that matches it. And it's timed! I ask students to shoot for their best time with 100%. One of my students made top 5 of all players in the world with 37 seconds. We have no idea how she could do that!!

Click here for the link at Purpose Games. In the past, my students have logged in and played the game to try to get their names on the leaderboard. I assign it for homework the night after teaching the unit circle and give a bonus point to the top 3 students. But this year, I found the tournament section!

I discovered that there are lots of things to do on this site, but all I have tried so far is to click on CREATE at the top and create a group.

You can name the group whatever you want and even can add a picture. Then click on create a tournament, in the yellow box. On the original, I did write some clever things, but for show here, I didn't.

Enter the name, description, and when you want the tournament to start and end. Save the tournament.

A few things to note: π/2 is not on there. Also, "x-cosine" means click on the button that is the x-axis, and "y-sine" means click on the button that is the y-axis. There is a glitch for quadrant signs. x,x means +,+, etc, so the plus signs come out as x's. Otherwise, it's all good, and my kids really enjoyed playing it. There was a lot of chatter about it the next day in class. AND they know their unit circle!
