I tell my students to log onto Quia if they finish a project earlier than the rest of the class. The activities help them to sharpen their knowledge of what we've gone over so far, and they feel like they're 'playing'. I believe that this has helped their knowledge of key terms we use in class. Love the self-grading tests!
