Parallel and Perpendicular Lines







Most of this unit involved writing, without fancy foldable flipping. I will share the purple examples, the Parallel, Perpendicular, or Neither Flowchart, and the sort activity on TpT. Our school is very limited on copies (1750 per semester, 2 cents each after that) so I copy most things as small as possible. This file includes many different combinations of the file so that you can choose what works best in your classroom. The purple examples print 3 to a page, and there is a filled-in flow chart and a skeleton notes type. Enjoy! Let me know if you try these activities.

Angle Pair Relationships Pages

I am way behind in my blogging, but here are some pics of our Angle Pair Relationships practice problems. Last year I did most of these on one page, with one example each and no written explanation. I'm hoping it went better this year, but their grades aren't showing it. My suspicions about the reasons for that could fill 10 blog posts. For now... here's some geometry notebook goodness. (Oh, and all of the printables are FREE on TpT)














Disclaimer (again) - I cheated "used my resources" on most of these pages and borrowed examples from wherever I could find them. I am but a humble math teacher, trying not to re-invent the wheel every single day. If I used your intellectual property, please let me know, and I will give credit where it is due. Thanks!

Angle Relationships Unit

In last years notebooks I did this unit in about 3 pages. I think my co-teacher thought I was crazy. So here are pages 13-22. Enjoy! (If my work computer ever gets fixed I will post these printables on my TeachersPayTeachers site for you to steal use in your classroom!

This page has both a spinner and a foldable.

3 Dimensional Figures



I got this great idea here and updated it (not much) for my high schoolers. It always surprises me how much geometry they are "taught" in the earlier grades that they don't remember once they make it to high school.
I like to have my notebook items in printable format, even if I make my students create them from scratch. It helps to have the option of just printing one for the kid that can't write legibly, or the one who freaks out about writing on something that has glue on it, or the one who takes 10 times longer than everyone else to cut... Did I mention I teach 16-18 year-old's?

Circles

We didn't even get close to finishing all the stuff on circles. We talked mostly about angles and arc measures. A little bit about sector/segment area and lots of vocab. Here's all our circle stuff. Enjoy!

 Page 44 - Circumference and Arc Length



 






Page 45 - Area of Sectors and Segments






 Page 46 - Inscribed Angles







And then my document camera stopped working. I created the next few pages using PowerPoint. My digital projector has zoom and freeze functions. I use those so that students can see what I'm working on in real time. 
(That is how I created PowerPoints for every section in the book. My coworkers were very impressed with me until I showed them that little trick. I would zoom in and draw all the stuff first block, then add all of the animations to it during my planning. Then I could walk around during my next two classes. I'm a big fan of "cheating" aka: "using your resources.")

Page 48 - Crossing Lines and Arc Measures

Luckily, my sympodium still works. That made filling in the examples MUCH easier. I could have done it in PowerPoint (because I am a ninja) but it would have taken much longer for the same result. This is a one-slide PowerPoint that is animated to show the flaps opening and closing. It is not easily printable.  Free here. 

We didn't talk about tangent lines or secant lines, or I would have used that terminology. We really ran out of time for this chapter so I stuck in whatever I could.
