I’m starting to wish every worksheet was available in flashcard form! They TALK about the problems, they ASK questions, they rotate/point to the problems as they explain, they debate, they make up games on their own… and they get to practice a million times over w/out wasting a million paper!

So with this set, in the BOX widget to the left, they simply have to identify if they triangles are congruent by which postulate/theorem or if it cannot be proven, say it cannot be proven. I gave them the cards right after teaching them SSS, SAS, ASA, and AAS. I had pulled out all the ones they did not know yet beforehand. After I taught them HL and the Isosceles Triangle Theorem, I added those cards in and gave it to them again.

TO PRINT:

Print pages 1 and 2 back to back, 3 and 4 back to back, and 5 and 6 back to back. Pages 5/6, however, are double sets so you only need to print half as many as the other two pages.

I printed a nice cardstock class set for myself (one per pair). Students use this in class and if they need to draw on it to explain to each other, I give them patty paper so they don’t mess up my cards. I also printed out a bunch of extra copies (not cut) on regular colored paper for students to take home if they need more practice.

I threw this last card in today because after training them on how to identify AAS vs ASA, for example, they forgot what these were actually proving to start

Fantastic review!
