I have discovered Edmodo! It is a great place for students to take quizzes and polls based off of school work. Students can take the quizzes during computer lab time or on their at home. Once they take the quiz I get the scores to see how they did. These quizzes could even work for a formal grade! Right now I am using a point system with the students that we are keeping track of on our blog. After they get so many points from taking the quizzes, they earn special badges for each level. Check Edmodo out!
