Hello! Please, help me to deal with this problem. I've never had a situation like that. My child is a very good student. We have never had any problems with any teacher. However, this year my kid got into the new class in November ( the same school, 4th grade) and has a new teacher. Everything was fine until the day when I received a test where a teacher made several mistakes. I contacted the teacher and explained the situation. She refused at first to correct the test. I made a copy of the test and sent her a letter where I proved that she made a mistake. After that, she changed the grade from 25% to 85%. I thought that this was over. However, my kid has been mistreated since. There were several incidents, however the last one is outrageous. Yesterday the whole class had a holiday party and every kid received a goody bag and a book. There are 28 children. Only one! student did not received the book. Guess who it was? I am afraid that the teacher would lower the grades. Besides, my child feels very unsecure and excluded. What should I do? Go to the principal? What should I say? What proof would be necessary?
