This is an intended audience from kindergarten to 7th grade, each game is classified in a group of games designated for a certain grade and subject matter. The purpose is to give students a fun way to apply what they are learning. I liked the activities and I think the games themselves were very good and user friendly. They really hit on the math topic and some of them are really challenging. I also like that they can compete with others or there are other games where you can go at your own pace.
