Trello is a website that allows users the ability to collaborate on projects and organize who is working on what within those projects. If you have students working on a long term project, this would be a valuable tool for them to use to stay on task. With the growth of PLC's and schools seeking accreditation or meeting standard requirements, this would be a good way for principals or superintendents to track the progress of projects designed to meet those standards.
Trello organizes your projects into boards and in one glance you can see what is being worked on, who is working on it, and the progress that is being made. It would obviously take some training, but in time, could be a great way to organize projects. For more information, see the video below.
