Partly it’s because I didn’t get really excited about it when I was in HS (although a lot of self-proclaimed math geeks really hit their stride in geometry), and partly it’s because the tricky part is honing their intuition when it comes to proofs.

2-column proofs (not that I’m in favor of them, honestly) lack that formulaic procedure that students like to latch on to. You have to get them to “see” what’s going on, and hone their intuition, so they know what theorem to use.

Not that designing a lesson plan or two around that intuition building would be impossible, but having to do it for a quarter or two?

But the geometry teachers at my school seem to use a really good book, and they have this magical box sent by the book publishers which holds a ton of worksheets and assessments. That set of resources seem to help them out. I can get you that info if that would help.

You’re going to be great at this in summer school.
