The best website I found was http://www.tes.iboard.co.uk/player/index.htm, where I found tons of games for all different subjects. They have math, science, history and geography games that kids can play. The games are child friendly and easy to play and understand. This would be a good website to use after teaching a new lesson so the kids can have a better understanding of the lesson. Another website was http://nces.ed.gov/nceskids/createagraph/default.aspx, where they provide quizzes that the teacher can customize by subject and grade. This would be a good tool to use for a daily or quiz grade for the students to measure their understanding of the lesson.
