This website can also be downloaded as an app on most portable devices, such as iPads, iPhones, and Kindles. If your student is in my class, they have an assigned username and password. If you would like to have that assigned information, please contact me via email or phone. All of the work on this app is individualized, so students can work at their own pace and on concepts they currently need to work on. Plus, they get to customize their avatars. They LOVE it!
