#MTBoSBlaugust Day 8: Geometry Scope and Sequence

First and foremost, I just have to tell you all that I'm continually amazed by math teachers in general and, more specifically, this community. Teaching is such a personal subject, something that we pour our hearts and souls into every day, and that can make us very vulnerable in our work. It would be totally natural for people to be private about their successes and their failures, as well as possessive about things we've created. But year after year, I continue to meet new people who are willing to share and help and it's helped make me even more willing to share and help. I feel privileged to be part of a community like this- one that I don't think many other subject areas have the pleasure experiencing. (My science-teaching husband is pretty much constantly jealous of the things I talk about people sharing and doing in the MTBoS :) )
Today I'm sharing what I've been pouring over all morning (between Olympic swimming heats, of course). I'm trying to piece together my big Geometry puzzle this year, as I've not taught Geometry since 2011 and I've never really taught with the resources of a textbook. My last district stopped buying them long before I ever worked there. Thankfully, in the true math teacher spirit, my amazing new PLC shared all their daily materials with me to get an idea of their pacing. I have tried to cross reference this with the standards and the sections where these things pop up in the text. We are using Holt McDougal Geometry (NY Edition). 

Any huge differences anyone sees with their scope or sequence? I am sure there are things I'll be revising, but I want to make sure I have a realistic big picture before I move any further. I'm still getting back in the Geometry saddle, so any and all advice and feedback are appreciate from the Geo pro's out there! 

P.S. No post yesterday, as my entire portable hard drive of a career's worth of teaching materials for grades 6-12 AND wedding pictures was seemingly corrupt for a short time. After rescuing the files, I needed a nap. 


  1. I might use some of our outline to beef up my class. We don't use CC as PA has its own standards. I LOVE flow proofs but stopped doing them, for no good reason. I might start again.

    We also don't do points of concurrency (and the properties there of) in triangles.

    It also looks like you do a ton more constructions.

    We miss radians, and law of sines/cosines.

    I taught geometry at my school for the first time last year and thought it was way to easy for the kids. Looks like I could take your outline to our department to show the rigor we are missing.

    Thanks for sharing.

  2. I don't teach Geometry, but just had to send some virtual hugs for the stress of your hard drive. I would burst into tears and/or cursing (or both) if that happened to me! I'm so glad it was recoverable!

    1. Thank you!!! I was doing all of the above, for sure!
