Tons of interactive white board resources - FREE ONES from @Tesconnect - I'm sending all of these to our kindergarten teachers. Lots of great free stuff. TES is in the UK so sometimes the terms are different but great resources.
"A superb online whiteboard suite of tools, including a random name picker, classroom sound level indicator, display a QR code, drawing and text tools, traffic lights, timers, clocks and dates, and even a fab exit poll tool. You can even change the background, including your own images to display extra resource information, or use your computer camera to show live video like a visualiser."
