Once you have finished your plans, you will find that your class runs much smoother than it would without it. For example, your students will enjoy the luxury of the daily routine and the security of knowing that their teacher will know exactly what the plan is on a day to day basis. Should a delay occur, such as a classroom discussion tangent or a school cancellation, you will nevertheless have enough time to reschedule various events. Writing plans are also useful in that if you plan to take any field trips, you will be able to prepare for these events ahead of time.
Fortunately, lesson plans can contribute toward both. In the case of teaching, these plans are often approved by a committee before they are presented to the glass. This not only ensures that the material provided is appropriate for the class, but it also reflects on the quality of the teacher as well. Once the plans are approved, the teacher is free to use them to educate his or her pupils. However, if the opportunity arises, adding a bit of spontaneity to the class will do wonders for helping to cement it in your students minds. Thus, feel free to leave a bit of wiggle room when planning your plans.
