My Christmas present to all teachers. An infinite canvas as your whiteboard. Supports images (eg photos of student work!) and multi-page PDFs (eg exam papers). Totally free. Merry Christmas, and enjoy!
Jake Gordon – December 22

See Jake’s YouTube Channel, Mr Gordon’s maths universe which includes an Introduction; the interface is very simple and intuitive to use.

I have mentioned Eric Curts before, for example see his introduction to Mathigon, a Control Alt Archive Workshop where he interviews Mathigon’s head of content David Poras.

His recent EdTech Links of the Week 1-2-23 features Jake Gordon’s Infinity Whiteboard.
