Our program like Pixie that works on the Chromebooks is called Wixie. You can find out more about it and give it a try at http://www.wixie.com
. Wixie is a cloud-based version of Pixie where all student work is stored in the cloud. Wixie also integrates well with the Google log-ins you are likely using with your Chromebooks.
Pixie is only available for Macintosh, Windows computers and iPads and Android tablets.
