When you click the button Start loop, a copy will be made of the loop you are in. Maybe you have clicked your way to the Library and into a loop that is there, or you are in one of your own loops under My loops. No matter where you are, the same thing happens when you click Start loop. A copy is made of the loop and you begin the process of starting it up with your students. The next step will be to give your distribution a name and to decide whether you want to set a date and/or let the participants terminate the loop on their own. Once you have moved on from the pop-up window where you do that, you will come to the Teacher Panel. That is where you invite students to the loop and activate it so that your students can start working.
