Goes over questions quickly. If you get something wrong on homework, he doesn't help you or anything. All I learned was right and wrong, not how to get better.

Mr. Hierro is probably knowledgeable, but he dosen't teach well at all. He never checks to see if anyone has gotten the content and when tests or homework comes he says "I told you in question 3.4.2.5.6..4..3.3.4.5..4.5." and dosent explain further.
Also the EST dosent help anyone.

MR Hierro has a storng way of teaching math. HE uses references from entertainment(LOST, Justin Bieber, Call of Duty, etc) to show how equations work.He is also very funny when he puts the bad kids in their place.

This is seriously one of the most dreadful math classes at Canyon. Hierro's notes are quite simple. That's the problem. When he drops the massive load of homework on you, you don't know half of the stuff in there because the notes were oversimplified. He also grades too hard. 2 points on each homework question? 1 mistake and it drops you into a B. And the STAR test. I felt so unprepared for the last 2 pages. Overall, this class is just... a no.

Had him two years in a row. Very repetitive. He uses old school teaching methods and has the same agenda EVERYDAY. Warm-up, homework, then notes. The occasional quiz/test or "activity" pops up. Notes are worthless. Basically he puts a buncha numbers on the overhead, briefly goes over it, and then moves on. Finally he drops a ton of homework on us and hands out detentions like they're candy. The year will be very stressful.

He singled out a student once bc of their religion. made them stand outside of class for 15 minutes every class. Rain or shine; this stopped after their parent was on verge of filing law suit.
