These are printable Team Color Badges for attendees to Duolingo Events Language parties! You can use them with your attendees to organise large groups into teams that will work together in language centers.
Each of the colors has up to 12 badges so you can have teams of 12 if you go by color, or you can use the shapes to make larger teams, or pair students up! You can even do even and odd numbers - whatever you like!
Just print them out, cut them out, laminate them, and superglue pins to the back. Cheap, and reuseable.
