NumberCoach works! It works because you need to get a question right 3 consecutive times. Each day you visit the site you can only answer each question once. When you get the question right on 3 consecutive visits you don’t need to do that question again.
Teachers and parents can log-on and see what questions have been answered, any mistakes that have been made and write comments to students.
