Project a timer on your iPad for your class

A simple and useful idea: Open up a TIMER app on your iPad and project it for the class when they are doing something for a given amount of time (group work, quizzes, transitions, labs, etc). It helps students budget their time, while freeing you from being the time-keeper. There are lots of free apps, including the "Clock" app that is on your iPad by default. I personally like the app called "Timer+" (available on Self-Service) because it allows you to store and label different timers, so you can quickly select ones that you use on a regular basis.
