When I taught it, I did popsicle proofs (similar to your cut out ones), but I organize them in terms of difficulty (great for scaffolding and differentiation). Each reason and statement goes on a popsicle stick and I place the given and prove statements on a index card and place in the baggie with the popsicle sticks.

Have wrestled with teaching proofs for years now and see a lot of overlap with what your tips. One thing I do as well is I have students draw each triangle that is part of the proof in two different colors. If any segments have two colors on them, they know this requires the reflexive/symmetric property to show the shared side is congruent. I also focused on circling any vocabulary words that are in the givens and explain that they should absolutely have a reason that contains the same word. So if a given says "M is the midpoint of AB", then they have to have some kind of statement that has a reason "definition of a midpoint". One last thing I do is as they are working through the proof, I have them mark to the left of the statements little a's and s's whenever they have proven an a or an s congruent in a step. This helps them both know when the proof is completed as well as help them pick a triangle congruence theorem to end with. Thank you for your awesome blog! :)Jillometryhttps://www.blogger.com/profile/09092561768252050872noreply@blogger.comtag:blogger.com,1999:blog-8268773079578019071.post-84118662092544603722016-10-25T19:55:07.163-05:002016-10-25T19:55:07.163-05:00I would also cut out proofs into each step --state...I would also cut out proofs into each step --statement separate from reason.
