Under the vocabulary and quizzes link you will find lists of words along with pictures that allow students time to study and then "quiz" their knowledge.

The interactive lessons were fun little games with sound clips to listen to before answering questions by clicking on appropriate spots. Not only were the games helpful and educational, they were fun as well!
