What does “getting along” with your teacher mean? “Getting along” means that both you and your teacher have a way of communicating and getting what you need from the relationship. In your teacher’s opinion, he or she wants to make sure that you are paying attention, being polite, and trying your best to learn. In your opinion, you want a teacher who is respectful to you, answers your questions, and tries to help you learn. You can get along and learn without being friends with your teacher, although it’s nice if that happens.

In every school, kids will say that some teachers are mean or strict, but don’t judge a teacher until you are in his or her class and can see for yourself. A strict teacher may be someone who feels strong about getting his or her job done — teaching you the subject you are supposed to learn. It’s also important to remember that making mistakes is a part of learning. By pointing out your mistakes and helping you correct them, a teacher is teaching you. Remember, in most cases, your teacher is on your side.

Even if a teacher isn’t your favorite, you can still have a successful relationship, especially if you carry out your responsibilities as a student. Here are some of those responsibilities:

●Attend class ready to learn. Be prepared for class with the right pencils and books.

●Listen carefully when your teacher is talking.

●Do your best, whether it’s classroom work, homework, or a test.
