Kubbu is a great Web 2.0 site w/ educational portals where teachers can create free student accounts (up to 30) and then create/assign them digital assignments such as: quizzes, games, puzzles, and more. Also, an educator can create "groups" and message or email students. Best of all, educators are able to generate detailed reports and track/assess student learning.
I highly recommend checking out Kubbu by clicking here!!!
