Intro Geometry Proofs INB Pages

Last year, I created several interactive notebook pages for beginning proofs in geometry.  However, this year, I'm teaching honors geometry and wanted to include more proofs practice in their notebooks.

First, we started with two-column proof tips.  I used this same page last year.  You can find the page on the link above.  However, I didn't write as many notes on the page, because I wanted my honors students to thoughtfully add their own tips to this page.

These interactive notebook pages are perfect for geometry proofs!  I always need more examples and activities for my algebraic proofs and segment and angles proofs notes.

Then, we completed this flipbook for algebraic proofs.  I had my students write all of the properties under the first flap and practice under the second flap.  On the last flap, we did a few algebraic proofs together.

The next day, we started segment and angle proofs.  I used this foldable so that I could have students add a lot of practice proofs into their notebooks.  When we did these examples in class, I had them fill in all of the "givens" first.  I want them to see that while proofs may have lots of blanks, there is always SOMETHING that's a "freebie".

Once students were more comfortable with these basic proofs, I gave them a few additional theorems.  These theorems aren't in our textbook, but I use them in some honors-level worksheets that I have made.  I don't think these are a big stretch for my honors kids.  In orange, I have written the shorthand that students are allowed to use on homework and tests.  This page is in the exclusive content are of my Geometry Foldable Bundle.

  1. I really love this idea and your approach to introducing proofs (a topic that I have been struggling with as a pre-service teacher). Do you find that students use these foldables (or any of the foldables that you have have) as references throughout the year, or do they only use it for the unit?

    1. I guess it depends on the exact topic. Most of them they use for the unit, but there are some foldables they will revisit throughout the school year. For instance, we do the midpoint and distance formula at the beginning of the year, but use it again in the second semester when I start incorporating coordinate geometry, so they refer to it again. They end up using all of their foldables when they review for the mid-year test and the end of course test though!

I love hearing from my readers. Thank you for taking the time to leave a comment!
