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.
Once you know what work you will be covering in the semester which lies ahead, you can move to weekly and then daily planning. A lesson plan must be a tool to assist you to be thoroughly prepared for the lesson itself. You can decide to spend a week on one topic, for example, an introduction to sentence types; then your weekly plan will simply be further divided into daily objectives and activities.
Step two of drawing up a lesson plan would be for the teacher to decide what resources will be needed for the lesson. The home school teacher might make use of a simple storybook to start. Thereafter, a series of worksheets for discussion might follow. Finally, the lesson might conclude with an assessment task, to ascertain how well the student has understood the work covered.
