It’s been about 3 years since I taught Geometry and there are people doing a lot more creative and deep-thinking stuff than myself (see: Jim, Julie, Lisa, Mimi, Shireen, and many others), but ugh, having to draw a geometry diagram in Word?

(Hint: draw it in Geogebra, then use the snipping tool to grab it and insert, but even then it’s a pain). So just to save you some time and hassle, I’ll also be trying to share my Geometry files this summer; stay tuned to this page! Since it has been three years, much of it will be presented without comment. 🙂

Ah, the dreaded first chapter full of definitions. I guess I hated it so much I didn’t keep many files, but here’s what I do have:

Oh, here’s one thing I’ve done that’s pretty creative: I made my own Angle Awesomeness Rap (I used to have a bit of a commute and planned it out on my drive one day). It even has a snazzy powerpoint:

(file here) And NoteTakerMaker:

File here. Yeah, I know, I’m the next Beyonce.

Then I guess I did some sort of other work, and then a review

Now for Chapter 2: Logic and Proofs. First up, logic! With symbols! And lots of corgi references!

Now…dun dun dunnnnnnn….. PROOFS! First, some properties:

File here. And hey, let’s figure out what we know from givens:

And then remind ourselves that We Can Figure Things Out (without a formal proof yet):

Then, we do the same problems with some proof handholding:

File here (and yes, the file has proofs for all 5 problems).

Then finally (finally!) we can start on some real from-scratch proofs:

File here. Also, look below at me being clever with using “G.I.F.T.” for proofs! And also Color With A Purpose. I also tell them that you should use every line in a proof, which is what the arrows are for. It seems to help if they’re stuck, “Well, is there anything you haven’t used yet?”

And also step-by-step powerpoints for the study guide!

Odds file here. Evens file here.

But I’m guessing we didn’t do so well on the test, as there is a “repractice” worksheet

And powerpoint:

So maybe now instead of making that 417th drawing in word, you can copy and paste from these and then:

Right?
