THEN, I discovered that teachers could create classes and assign these games to their students.
THEN, I realized that when students play the games, they get points and compete against their classmates.
THEN, I found out it is free right now during a beta testing period and for those teachers that sign up now and use it, they'll get half off the 199 per year price once the beta test is over! Note: The games will always be free--the classroom management portion will have a small charge.
I had fun playing the games as a 32 year old so I feel pretty confident students will like them too. Check out this website. It's very easy to set up a class and a quick startup for the students.
