A quick look at how to start using the Reflection App on your Mac so you can share your iPad/iPhone screen. The cool thing is you can move around the classroom with this app on and iPad or iPhone camera on and have a “portable, wireless document camera”!

Download the Reflection App. Part of the student-created Mathtrain.TV project.
