As I was looking at Mandy's blog and her post about Superteachertools, it reminded me of this app that was shared at a technology meeting we had earlier in the year. At the time you had to pay for the app, but they offer free versions of it. The app is called Groupinator and it is great for organizing you students, randomly generating student names or making random or pre-selected groups. You can upload students or create students for different classes and add their pictures. Below is a 4 minute tutorial I found on YouTube on how to get started.
