Last year I taught out of the McDougal Littell 2004 edition of Geometry Concepts and Skills. It was pretty watered down for a geometry course. This year I'm looking at the 2010 Glencoe Geometry book and it's a big jump. I will definitely be taking out a lot of these standards/sections.

Last year I did not teach similarity and one geometry class missed out on surface area and volume while the other missed out on circles and trig ratios. I don't want to talk about it. Anyway, I've never used this book before but so far I like the sequencing and for Illinois folk there are tons of PSAE problems, which is a plus.

I spent a few hours typing out these standards to build a concept list from and now my twitter friends are kind of talking me out of it. So, I may pull out my last year's Geo text and do those as well and combine. Or something.

Anyway, the list is huge and I made some notes and such along the way. So check them out and let me know what you're thinking.

All standards in red are ones I plan on chopping unless you say otherwise!

What should I eliminate, combine, rewrite, or rearrange?

I don't like how often it just says use, apply, recognize. Those words are somewhat vague. If I am a student how do I know that I used it right, applied the right thing, and recognized what I'm supposed to? It seems like they should be written differently in order to clearly assess.

Actually there are quite a few that I would really like to break down even more, but there's already 166 standards! That's ridiculous!
