Magnetic Proof Pieces
One simple thing I've done this year in teaching congruent triangle proofs is I printed and laminated some of the most common reasons found and attached magnets to them.
I also drew up three common "facts" that we look for when the information in the given is not enough.
This has been great for students to refer to while they are writing proofs. On one section I was able to tell them that every reason came from one of those pieces and that helped students complete proofs instead of leaving some parts blank.
I still don't know why they want to really throw out 'definition of midpoint' when the given says 'bisect' but you can't fix everything!
