I've hacked together a data collection tool with the Desmos API for an activity tomorrow - I'd love if you could help me test it out.
Please visit https://emwdx.github.io/groupData/index.html and enter 3DR9 as the name of the data set. Then enter an ordered pair in the form (age, # of years teaching).
If everything works correctly, we'll be able to put together a data set across the world and see it graphed in real time.
I'll talk more about this soon - thanks in advance for helping out, folks.
