Manga High is a new site offering free mathematics games for K-12 students. There are four games and a quiz program that offer graduated activities. Students earn gold, silver, and bronze “coins” to track their progress. While the games and quiz program are free, the rest of Manga High is a fee-based service.

Applications for Education
Manga High, like a lot of mathematics games sites, provides an intuitive and engaging platform for students to use to practice their mathematics skills. One of the benefits of Manga High is that it doesn’t have the intrusive advertising that some mathematics game sites have.
