In addition to the games, there are both lessons and tests for every one of the 1200+ elementary 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 elementary learner should work through before attempting the games.
When you are comfortable with the topic you might like to attempt the two simple elementary 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...
Elementary topics
Each of our elementary math topics is between 4 and 20 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). Most answers also have a speaker next to them which will speak the answer if you click/tap it.
