Might be really missing something obvious here (sorry) but is there a way to allow another teacher to see a dashboard at the same time?
A shared dashboard feature doesn’t exist. The Desmos Team has received that request fairly frequently, so I know it is on their list, but I don’t know how far down the list it is. I think there are some privacy issues that are difficult to navigate.
They just pushed out an update a few days ago with a new co-teacher feature. I don’t think it will allow two teachers to work on the same assignment at the same time, but it will let you both see the same dashboard!
