Best teacher at Algonquin hands down
His teaching methods are thoughtful and effective. Very lucky if you have this teacher!
He seemed really odd to me. I guess I just didn't get his sense of humor. So looking forward to next year.
Nice guy, smart as heck, very funny....just pay attention!
probably one of the best teachers you'll ever have-prepares you soo well for college and the real world.
Best to get him as an upperclassman as he is more open with the class. Lots of fun in BC calc and I think almost everyone got a 4 or 5 on the AP test.
Awesome. Sometimes quirky, but cool. He has a subtle sense of humor, and you have to be rather well-read to understand some of his jokes. Very clear about concepts when teaching, too.
Best teacher at Algonquin. Had him for Geometry, BC Calc and Math team. He is highly organized, efficient, helpful, funny, and was able to put up with Ashwin.
Explains things so well, whether in Geometry, Calculus, or Math Team.
Not only a great teacher, but a great person. One of the few at Algonquin.
He can be a good teacher at times, but often lacks the human interaction skills and lacks the desire to help kids out.
I have him for Calculus and he explains things so well!
Exceptionally well-rounded - he can understand pretty much any "nerdy" joke you can come up with and laugh with you. He's very neat on the board - straight lines, perfect circles, etc.
I think he was the coldest and least responsive teacher my child has ever had. He should learn humility.
i agree with the last poster. the man knows so much about so many things, it is just unreal. he talks about existentialism in ways that my english teacher could never explain. just a great teacher!
He's more knowledgeable about literature than any English teacher I've ever had. He does not patronize his students; rather, he treats them as equals, even though he's intellectually superior.
He is the coolest geek ever!! He loves math, but is funny too! And he knows so much stuff, he 's like a walking encyclopedia. He cares whether or not his students learn. Best Math Teacher Period.
Excellent math teacher. He is very organized, explains things well, and he's helpful. Extremely quirky, but it makes class fun. I've never enjoyed math so much.
HE IS THE MAN!!! He really knows his stuff and even does High School Football predictions.
Mr. McGrath is amazing. He really knows his stuff and he really knows how to teach it. Also, he's incredibly neat on the board and all of his lines are unbelievably straight. He makes class funny.
Pretty much my hero. Class is always funny but you also really learn things and he's willing to help you out if you need it. Definitely one of my favorite teachers.
Probably the most helpful, understanding teacher, especially in a subject like AP calc. He is always willing to spend extra time with his students be it before or after school.
MCG RULES. coolest math teacher ever. bunny cookies =!!!!!! plus his room's all decorated at x-mas. and he wont make fun of you for coming back to visit. A plus - he's super neat & organized so you'll never have to squint & be like "what's that say?" yeah McG's the man (hi!! i know you're reading this right now.)
I hate math and I honestly loved his class last year. He teaches in an extremely clear manner, and he makes sure you understand no matter what. Plus, he's hilarious. I loved him last year, and my class this year makes me love/miss him even more!
McGrath is the best math teacher ever! funny in his own way. Bunnie Cookies!
He is an awesome teacher and really explains everything well to make sure everyone understands the material. He makes jokes in class and he's funny - I look forward to his class every day.
He also coaches Varsity Math Team which is just a blast.
BEST MATH TEACHER EVER. He is an INCREDIBLY nice and flexible person, and is very funny in a subtle way. Very generous and dedicated. His syllabus is a very useful tool for time management.
umm great teacher, but he thinks hes funny and makes fun of some students, but you can get away with pretty much anything
I had McMath for a class in '00. He was fair, helpful and clear with all of his teachings. I found him to be the best math teacher I had before college.
wow i love mr mcgrath. i had him frosh yr for geometry and he STILL remembers me. he really cares about the students and he knows his stuff...i am just so sorry i didn't pay more attention in that class and ask more questions!
best math teacher ever. easy if you try. makes class fun in a unique way
Mr. McGrath is definetly one of the best teachers I've ever had. He's really funny, but I still managed to learn the most in that class this year. It's worth being in Geometry if you get Mr. McGrath!
Super cool guys who loves math and his students. Knows his stuff really well. He is funny too. My fav teacher so far in HS
I had him 3 times, and they all were great. Calc BC was an awesome class. He is my favorite teacher from all of high school, and better than any professor I have had so far.
Mr. McG... Sean McGrath, by far the greatest math teacher in Algonquin. He is the sole reason I decided to take a second major in Math at WPI. Thanks Mr. McG, you changed my life.
Once upon a time, there was a math teacher named Mr. McGrath. He is the Man. The End.
This guy is so smart. He knows more than just math. Great sense of humor and cares about his students. Best math teacher ever!
There is no better geometry teacher. If you pay attention, you will ace the class
Micky-G is the elvis of teachers!he rocks my socks off.Not only does he explain things super well and make class a happy place but he's got a sweet personality!
He's so funny. It's hard to believe, but he makes math fun!
Mr. Mcgrath is the man. Thats it. End of discussion.
Tests and stuff easy enough to me. Class is often fun, but every once in a while its boring business
he knows his math but is SUCH a stickler w/ points...doesn't like to explain sometimes
Best math teacher. Really, REALLY knows his stuff. Has perfect writing. Emphasizes the how's of math, which is what it's all about. Unique character.
mr. mcgrath is a great math teacher. he probably doesnt like me but i think that he is cool.
Best math teacher ever! Although i get the feeling he isn't particularly fond of me...
I love Mr McGrath. he is the coolest math teacher ever!!!! Start the day off right with Mr McGrath 1st period.
Don't pass up an opportunity to learn from this man!
McGrath is an awesome teacher, he explains everything so clearly, in a bunch of different ways. Math has never made so much sense before!
McGrath is the man, one of my favorite teachers ever. Join the math teacm, he is a great coach.
Mr. McGrath is excellent and by far the best math teacher in the school. If you draw him for geometry, you've hit the jackpot.
Definately a great geometry and calc teacher, always willing to render help when requested, makes the class quite interesting sometimes, decent class overall
He is an amazing calc teacher, and can help you understand anything.
