In addition to the games, there are both lessons and tests for every one of the 300+ secondary topics here at Free Math Games. The lessons include an introduction to the topic plus an "Either / Or" activity and a multiple choice activity which you the secondary learner should work through before attempting the games.
When you are comfortable with the topic you might like to attempt the two simple secondary tests available with Free Math Games. The writing test is a chance to type in your answers to the questions and has quite a funny help system which may or may not be that helpful...
Each of our secondary math topic is between 14 and 40 items - either equations, words, or series - as questions and answers. If you choose to have the robot voice on, the questions and answers are spoken by your friendly local android. If you didn't catch the question, click on the question box to hear the question again (and get an enhanced view of the question).
