This year, I taught geometric transformations at the end of first semester.  It’s a unit that is easy to move around and I needed to fill a...

I taught Segments in Triangles as a mini-unit this year.  I spent one day on midesgments and two days on altitudes, angle bisectors, perpen...

I love using this paper folding activity to help students discover the Triangle Midsegment Theorem.  This year, I had my students fold the ...

When I’m teaching congruent triangles, CPCTC always ends up being such a short lesson, because it seems so obvious to me.  That’s been ok f...

I think Congruent Triangles is my favorite unit of Geometry.  I also really like Right Triangles…  Anyway, I wanted to share some of the in...

To finish up our Parallel Lines unit in Geometry, we talked about equations of parallel and perpendicular lines.  You can find the pages fo...

I just tested my students over parallel lines in Geometry and they did much better than I expected!  Their proof skills are improving so mu...

I spent longer on my Intro to Proofs Unit than I typically do.  As I mentioned in my post about my Logic Unit , I typically combine logic a...
