Description: plash Math’s game-based content targets Common Core math content for kindergarten through fifth grade. Once on the site (or Chrome app), students choose a grade level before playing a series of animated games and activities. The student dashboard gives kids a starting point, allowing them to pick specific math concepts to practice. Students, teachers, and parents can see data on time spent on topics, accuracy, and level of mastery. However, reports don’t include info on Common Core coverage.
