There are many approaches to writing lesson plans. Some instructors develop their plans independently from scratch, while others borrow plans from a shared curriculum. Some carefully write out all the details for their lesson, while others use a brief outline. Your approach to writing lesson plans will depend on various factors: how well you know the material you're teaching, how long you've been teaching, the kinds of teaching you've done, and the students you expect to have in your class. There is no single formula for writing lesson plans, but this guide will help you think through some of the processes that other instructors have found valuable to their own lesson planning.
