I have been fortunate to be a Wonderbox EDU Ambassador. As an Ambassador, my students and I have had access to this app during beta-testing. They LOVE it! As a matter of fact, they loved it so much that they insisted on doing a review! If you'd like to learn more about the app, watch the video or read the full review at http://www.teacherswithapps.com/wonderbox-edu-wonderful/.
