i never really understood his way fo teaching. he would go into unecessary, high math proofs that had little relevance to what we were learning, and i found my mind wandering. doesnt collect hw, so litttle motivation to do it. but, easy tests and nicest man you'll ever meet!

I found his classes pretty easy, but he made math fun with his great personality. Look forward to the puzzles before class and his birthday song.

The best math teacher in my experience. He made things that other teachers made complicated so easy. He's really into math and it shows. He's always willing to answer questions clearly for everyone.

At first I did not like Mr. Penner, but after having him for two terms he's the man. He is also helpful and mad chill.

Cool dude. I learned a lot about proofs from him. He likes to joke about my obsession with theorems having names. Sometimes, he gets sidetracked, though...

He's a math genius. Problem: Our course is full of people that aren't so clever. He's quite hard and doesn't help you unless you talk to him.

Clearly loves math, but I couldn't tell if he was really that into his students. He definitely didn't recognize me outside of class.

Mr. Penner is possibly the best math teacher ever, very chill. He doesn't care much about the technicalities, his biggest goal is to make sure you learn the material in a way that makes sense to you. Pay attention in class and you're set.

Penner loves math. And he wants you to love math. Even if you're not into what he's teaching, but something else, he's willing to work with you on that on the side... as long as you don't need to use that time to work on your falling math grade :)
