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 for me in the past. However, this year, I think I should have had my students work with CPCTC a little bit more. I’ve been trying to keep up with our curriculum map, only to find out that it’s incorrect. I could have spent more time in this unit and I wish I did!
Anyway, this is the page I used for CPCTC. There are zero fancy things on this page. It’s actually kind of lame. I had the students copy down the proofs themselves. Yeah, I’m not doing that again. I have too many LD students for that to be a good teacher-choice. I want to make a little proof booklet for CPCTC like I did for parallel lines and triangle congruence shortcuts.
Also, learn from my fail. Don’t have kids copy down the whole proof themselves. :) It ends up super messy and illegible.
