Work Day

Brianna Heggeseth

As we gather

Sit with a group of a total of 2-3 people to work with on Group Assignment 3:
- If you are in a group of 3, you may only repeat 1 partner from Group Assignments 1 or 2. In other words, you need to have at least 1 person in the group you haven’t worked with on a group assignment.
- If you are in a group of 2, you should work with someone you haven’t yet worked with on a group assignment.
- Introduce yourself!
