Great math teacher, you can tell he knows his stuff.
Mr. Lastra u r a good teacher. Explains math problems really well so its easy to understand.
first time I ever passed math with a grade better than 65
breaks down math concepts so that they are easy to understand. will go over math problem until you understand it.
Mr. Lastra can't teach, he can't explain anything, and he doesn't even know his own subject.
