Prior to the Challenge launch date:

Create a Canvas Challenge course template for your Challenge. You should be enrolled in the course as an instructor.
Schedule your Kick-Off meeting (date, time, and place), and update the Kick-Off Calendar Event in your course template.
From the course Calendar, drag-n-drop each Challenge (Assignments) to your selected dates (also update the Kick-Off and Show & Tell Calendar Events). You can choose the frequency of your Challenges, but it’s best to choose a start-to-end timeframe of two-to-four weeks.
Update your pre-populated Announcements to delay posting until the date you have chosen for each Challenge. Your Challenges will be communicated through Announcements. You can delay each Announcement’s posting date by clicking the edit icon for each Announcement, clicking the Delay Posting checkbox, and updating the posting date. You can also customize the message in each pre-populated Announcement. Click the Save button when you are done.
Customize your course content. The course template includes sample content to give you a head start. Most of the items also include a “NOTE TO CHALLENGE LEADER” in red font. These notes provide tips and options for customizing each page/task to meet the needs of your institution. Read through each item in all three modules (Kick-Off, Challenges, Show & Tell) to gain an understanding of what is required and to customize the content. Edit any of the content in the Pages or Assignments as necessary. When you are finished, remove any red “NOTE TO CHALLENGE LEADER” items.
Create an EtherPad or Google Doc Collaboration with a list with each participant’s name. Participants will access this document early on to describe their unit of choice, and again at the end to share what they’ve accomplished.
Record and embed an intro video on the Kick-Off page about course shells. In your intro video, introduce yourself and explain what the participants will accomplish. Each participant will build a course within a course shell—you can either create a course shell for each participant, or you can instruct them to create their own. If you choose to have them create their own courses, have them add you (the Challenge Leader) as a Designer in the course. You will not be able to view their content if you are not a Designer. Ideally, the participants should complete their challenges in a fresh, unpublished course. Using a course with pre-populated content will make it difficult for the Leader to determine whether the task was completed during the Challenge or prior to the Challenge. Additionally, the final Challenge requires the participants to publish their courses. This Challenge will need to be substituted if the participants are already working out of published courses.
Enroll the participants in your course.
Publish your course.
