Mathopolis has several games for students to practice basic math skills. The Games section encompasses addition, subtraction, estimation, multiplication, division, percentages, length, area, square roots, fractions and decimals.    Mathopolis tracks your highest scores, and shows you how you’re performing compared to other players.

The Questions section provides additional problems and guided practice to help K-8 students master math skills.  The skill sets range from basic numeracy to pre-algebra.  There are daily problems,  mini-courses, and a quiz database searchable by skill set and grade level.

Registration and login is required for competition mode. A nice feature is that you can toggle ads on and off.  A smartphone app version of the site is available for a fee.
