Yeah.

Uh, it's within maths, right? So it's within my subject.

So all I have to do is mix things up.

And so I think it was a, a, like a year nine, year 10 lesson, and I'd previously been teaching them some probability stuff.

This lesson was on Pythagoras' theorem.

And so, you know, I introduced Pythagoras' theorem, we did a few examples, and then the next slide, I'd already planned it, was, uh, to go back and do some probability stuff, um, at which point, basically, pupils' faces just went blank.

Right.

Like why am I doing this for this and not for the other thing? But often what will happen is there will be an inherent spacing.
