Where do you go to build up the math skills of a junior high or middle school math class? According to our Grade 7 Math teacher FunBrain and CoolMath are two great sites to try. They both feature a fairly wide range of games and other activities. They’ve got bright colors and silly graphics that often appeal to the younger math student and annoy their teachers, and CoolMath even has a cursor on the main page that trails a string of numbers.
