This is part three of my first unit for Geometry. You can go back and read about part one and part two.

### Day 5 - Measure and Classify Angles

I used the Measure and Classify Angles Flipbook by Lisa Davenport. I really liked the flip book, but it was a little long for one class period. I liked the tab for the Angle Addition Postulate a lot because it also includes bisected angles. I wish I would have copied it on colored paper. Bright yellow would have been nice. Also, I wrote the wrong title on the page in marker and had to scribble it out :(

### Day 6 - Angle Pair Relationships

My students came to school with lots of questions about their homework. So, I made up this page on the fly before we started the new lesson. I think this is the bones of a good page. I want to do the same thing next year, but I will have the diagrams printed so the kids can glue them in. It’s so hard to freehand decent-looking diagrams in the interactive notebook.

This page has my foldable for angle pair relationships. I didn’t talk about the tabs in order. First, I talked about complementary angles, then supplementary angles. Then, I moved the the top tabs.

The last page for the unit was this Angle Relationships Error Analysis worksheet. We did this worksheet together and my kids did a super job finding the error. I wanted to explain the mistakes only using true statements. I didn’t really explain this to the kids, but I was trying to create muscle memory and pave the way for proof writing.

After this, there is a quiz, review, and the test.

That’s it! As we went through the unit, I ended up adding a few more pages than I planned originally. It makes me a little nervous that I’m going to run out of room before the end of the school year.
