From Jake Gordon, a Christmas present (2022) for all teachers! It will be really interesting to see developments on his resource – an infinite canvas to use as a whiteboard in 2023. 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.
