How to turn on a unit

I am substitute teaching and need to make Unit 3 available to the class. How do I make it available?


The ability to turn on/off a unit is only available through the teacher account. If you are able to log-on through the teacher’s account, you can change the unit by following the directions in this support document. If you are unable to log on, you will have to wait for the teacher to return. Sorry for the inconvenience!
