About my favorite teacher in new school

My favorite teacher is Mrs. Duarte! She is my teacher of math and my homeroom teacher. She is kind, but not in class-time. I`m not good at math, sometimes I can`t understand math, she always give me an advice after school. If you ask me why I like her, I will answer you because she always explains me everything, what i don`t understand. I remember this moment, when I came first time in this school, It was first of September, I first looked at Mrs. Duarte, I didn't know her at that time really, but I looked at her because she was similar to Ukrainians, I was guessing, " What country Is she from?" And I remember at the early school, I didn`t know everything, I couldn't understand everything, I was written work worksheets on math very badly, Mrs. Duarte saw this and said me to ask her after school, what theme I couldn't understand, and after this I am writing homework perfectly. And when for example one of my classmates says something funny, Mrs. Duarte sometimes smiles, sometimes she says " you can`t say anything on lesson!" Then I don`t remember anything funny, what was in her class, sorry :( . I think that`s all that I can say about Mrs. Duarte, because I`m new student in this school, so i know just a little now, but then I will write more...
But I can also say who are my four favorite teachers in this school: Mrs. Graves, Mrs. Duarte,
