Some of these Mission checklists would include:
Google Network Login set up
Google Passport Idea (Do I know how to attach a Google Doc? What is the difference between the Stream and Classwork tab in Google Classroom?)
MiStar Student Connect Access
Clever Apps and Integrations
Other ideas for this page would be help guides for questions students ask a lot. Similar to this How to check grades slide deck
One main challenge with this site would be how to get students to use it regularly and as a way to help support their own learning. I am imagining teachers linking it in their Google Classrooms as a resource.
