Is it true that a teacher can teach what they want? As in if you do not like a certain topic or chapter in a book you can completely skip it? One of my teachers said that he/she could teach us what ever he/she wanted. The teacher said he/she did not have to use the book at all. The teacher told us that his/her teacher did not show us the current stuff we are learning. I know that can definitely happen as I was never taught how to factor a polynomial in Algebra 1. I acquired the skill later on even though I was told I should have learned that skill in algebra 1. Also I know in Geometry we skipped several sections and I am hoping this does not some how backfire on me. If one of my future teachers skip a topic will I be learning it in college? Or would I just be expected to teach myself as a Math Teacher?
