Lesson plans are an effective tool in the hands of a teacher. If for some reason, a day is disrupted, you can simply refine or combine two lesson plans to cover the following day. A lesson plan must not restrict the flow of learning and teaching. If you have planned to cover a certain amount of work and fail to do so, there will always be an opportunity to move onto the concept in a follow-up lesson. Home school teachers who have difficulty being flexible, would be well advised to plan their work in lesson units and not individual lesson units.
Step one for any lesson plan would be an outline of the objectives of the lesson, the why of the lesson and its intended outcomes. Your objective would be stated as, for example, by the end of the five lessons, the student will understand the difference in usage between a statement, exclamation, command and a question. In addition, the student will make use of the correct punctuation marks to indicate the different sentence types.
Step three of compiling a lesson plan must assist the home school teacher to envisage the lesson as a unit of time. Each lesson should in reality have an introduction with introductory activities such as questions posed verbally; followed by a body of the lesson with further activities and exercises. One should also always have a clear conclusion in mind, to summarize and tie up the new concepts covered for the student.
