A+ Click helps students become problem solvers. No fees, no ads, no calculators, and no sign in. The website features a graduated set of over 4300 challenging problems for students in grades one through twelve, starting from the very simple to the extremely difficult. The questions are based on the Common Core Standards in Math and go beyond by adding hundreds of meaningful practical problems and brainteasers.

The questions concentrate on understanding, spatial reasoning, usefulness, and problem solving rather than math rules and theorems. The problems include a short description and an illustration to help problem solvers visualize the model. The problems can be solved within one minute and without using a calculator.

The tests adapt to student ability. To progress to a higher level, you must correctly answer five consecutive questions. Younger kids in grade 1 through 5 have two chances to get it right. If you correctly answer 16 questions, the system suggests you enter the competition. The self-study learning site includes game elements: star scoring system, cheering sounds for young kids, statistics, and a Leaderboard. The Leaderboard shows the best peformers of the last 10 days.
