How do you reach the same level of effectiveness teaching or debugging math problems on a whiteboard without investing a lot of time asynchronously?

If I may be so bold, we've taken a stab at this: https://sharetheboard.com

Our focus was originally on shared whiteboarding (PdMs + devs) but in 2020, for obvious reasons, schools started contacting us and using the tech for remote/hybrid teaching.

But it's true: the real-time part of teaching/writing/debugging is critical in the learning process. For this same reason, many of the teachers we work with use our app to share a piece of paper in real time. Similar result and you don't have to own a whiteboard.

(if you get a chance to kick the tires on it, I'd love some candid feedback)
