MathMovesU is a great math site for students grades 5 and up. There are three levels: grade 6 and below, grade 7, or grade 8 +. Each player chooses their own character and customizes it before beginning their journey. Once created, your player walks through scenery. As they walk they encounter math problems that appear in boxes above the character's head. Points are earned by answering math questions correctly. There are games, facts, and quizzes that also appear in their path. A super fun way to get kids interested in and engaged in mathematics!
