Here in Maryland, we are forced to have kids prep for a number of exams as well as classrooms assessments (tests and quizzes). Often for kids who cannot or do not take good notes, a review of material is a must. However, time is of the essence and in the school day, there is not always time to review. So, I have begun to use quia for review. It has several ways to review...quizzes and games. Both of which I have found to be of great value. The quizzes save me time as the computer grades them for me as long as I have put in the proper answer key. The review games are valuable for those who need something a bit more interactive.
Another site that I like for review games is this game. This does the same thing but with a sports type theme. Kids can take a shot on goal in soccer or a 3-point basket in basketball for each question that they answer correctly.
Scores here have gone up, so they are working.
