Flash cards were pretty good math practice. But, they were always the same math problems, over and over. Lo and behold, Math Quiz to the rescue! Just select the difficulty level then click the type of problem you want to practice with, (add, subtract, multiply, and divide) and Math Quiz will pop up a problem for you. And, a built-in score checker grades you along the way! Great practice for elementary-aged students just learning their math skills, or for anyone wishing to practice a bit!
