Lesson plans are essential in classroom management, course structure, class preparation and being organized. A teacher that becomes well versed is one who can feel for the population of students and their needs, along with having the ability to be flexible in case of time in the classroom being not as expected in actual teaching of the lesson. Being able to anticipate any changes, be they small or noticeable, can be best done with a framework, and lesson plans help to provide that framework.
Knowing ahead of time of what you are going to teach saves a lot of time, frustration and headache for a teacher. Organization helps keep a teacher focused and on task, and the lesson plan is the blueprint to gauge the students' progress both in real time and over a course of time. Like what was stated in the module, it also provides documentation for the teacher, as to his or her own progress, accomplishments, and documentation for what was achieved or not accomplished, so that it can also serve as a plan for the future
