What's the Purpose of the Show Call?

I think I don't know if the video cut out, but I gave them a similar question. Sometimes I do. And sometimes I get the mini whiteboards out. That would be in the second video. So you basically, they'd got it wrong. You'd explained it that had another go and then you were show calling. They'd all done the same task, right? Yeah. What did you want them to take from it?
