What do we call the pen using for the interactive whiteboard?
What do we call the projector showing image on the whiteboard which normally hanging on the ceiling.
When the whiteboard doesn't work, I saw the teacher using the pen tipping on the corner to activate. I heard them using a special single word to describe this action. What is that word?
Any mistake in the above writing?
Pen and projector can be used. Not sure about the third.
