Proofs take time to learn. They take an even longer time to get good at. I have been trying to tackle proofs from every direction I can possibly think of. The latest of which is called Pass the Proof.
Here is a quick rundown:
- students break into groups of four
- each group gets a sheet that has 3 proofs on it, each looks something like this
- each student has three options; fill in a statement, fill in a reason, or erase one of those two.
- After doing so they pass the sheet to the next person in the group.
- Repeat till Q.E.D.
I made into a game. The first correct group received 3 points, second – two points, third – one point. We briefly talked about each proof upon completion.
I really enjoyed this activity!
** Update ** Here are the proofs I used.
