Sync with Other Calendars

Activity: Collaboratively create a "master" school calendar. 

Note: I recommend keeping your original calendar as a personal (or professional) individual calendar.
Each team member will create a new school-related calendar such as:
  • Staff Meetings
  • School Events
  • Athletic Fields
  • The Library 
  • Computer Labs
  • ASB
  • PTA
Others in the group will subscribe to the various calendars to create their own "Master Calendar."
Experiment with different permissions on calendars... so others can create events (or not).
One person from each team will share their "Master Calendar" with the large group.

Note: After the activity, feel free to unsubscribe from the calendars created today, so that they don't clutter up your "real" calendar.

Bonus Functions

Bonus: Embed multiple calendars in one page!      
Bonus: Schedule multiple resources in one calendar (only in Apps: Education Edition).
