### Mathtrain.TV, Ep.110, Reflection App for iPad

Saturday, April 21st, 2012

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”!

If you want to show it on a projector, just remember that you need to have an adapter to go from your Mac to your projector (which is most likely a VGA connection).
