Triangle Congruency Foldable

This is a great way to help students with the triangle congruency shortcuts.  They can easily glue it in their notes or stick it in a folder.

Proofs....Everyone's Favorite Thing to Learn!

Proofs can be tricky- especially when it comes to reasoning through our thoughts.  I have found a great way to help the students begin to reason through proofs is to start simple.  I have used in the past many times this great Proof Envelope Activity.  There are four stations that the students need to complete.  Proofs 1A and 1B go together because they are pretty short.  I have the students work in teams of two but no more than three.  Once the students have them completed, I have them take a picture of the work and put them all in an electronic document of some type.

The next class period I see them, I then give them a few more proofs to work through together in groups.  This time they do not have word banks and have to think through the proofs a little more.

Hope this can make your teaching of proofs a little easier!
