Cool math games is a fun,educational,free website that kids can play games on,while learning!
Games quality: the games are fun and can be found on other websites.some games are made by cool-math.but I don't think the games are very educational.
Background: the site is by a teacher who saw that students wanted to have fun by learning,so I would use it as a teacher
Who uses it? Kids at home ,schools,.But most teachers use it for free time instead of math time,which is agreeable because some games are not math based at all.
So the site is okay,but not very educational.
