If you've ever used "Clock Partners," this is my spin on that technique. Have the students fill out the Instagram followers with people they want to partner up with during group work in class. They should write each other's name on the SAME number space. For example, if I want to partner with Emily, I'll write Emily on #6 and she'll write my name on #6 on her sheet. Then, all you have to do is call out a number and you have partners! Ex: "You're going to work with your 8th Instagram Follower for this assignment."
