So, I'm a new teacher, planning my powerpoint and curriculm, worksheets, warm-up sheets, and grading seems to be taking over my life as it is. But I have a huge gap in ability in my precalculus class, where some fast students complain that they already learned the material. What I currently do is try o type up challenge extra credit for them, I have no other way to manage that, but it adds more to my work load. My coach wants to get me to differentiate, but he says I'm not ready yet. What do you do? Help?
