Surface Area and Volume

I made this foldable to put all of the formulas on one page. It has saved time and allowed more space for practice. I just do one or two examples from the worksheet for each shape.

For the students I teach, the textbook doesn't have enough practice problems that are simple enough. One, maybe two, then they're off to multi-step, challenge problems. I use KutaSoftware to fill the gap. I purchased Infinite Geometry a few years ago and I love it. (They're not even paying me to say this, but they totally should.)  The free worksheets are great... but kids are smart. Mine figured out pretty quick that the answers are online. Is that considered cheating, or just using your resources? Now I just make my own. Problem Solved.

Special Right Triangles

I teach Special Right Triangles using proportions. My students create 2 notecards: one with a 45-45-90 unit triangle and one with a 30-60-90 triangle. The students never really understand why the 30-60-90 notecard needs two versions. They just know that it works.

With this unit we also do a review of rationalizing denominators.

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!

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?
