This game introduces students the basic word roots in our language. I recommend having students use their word study notebook as they play the game. They can keep track of the roots that are introduced in the game and use them to begin their study of roots. When you go to this site you will be asked to sign up for Quiz Lab. There is a huge section for spelling quizzes.
Teachers can create their own quizzes and have students log-in to the web page and take the quiz.
Instant feedback answers are an option. Students quiz results are emailed directly to the teacher. The quizzes that are pre-made by other teachers are not all good. The biggest problem with these pre-made quizzes in spelling is that most of them are multiple choice with 4 misspelled words and word correct word. I do not recommend this as a testing method.
