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.
Obviously, an effective teacher will plan for a whole phase or at least year to begin with. The best way to start the four step process to drawing up a lesson plan; would be to begin with a broad overview of the skills, knowledge and desired outcomes for each quarter of the academic year. One can simply plan to make a one page annual summary per subject to be taught. If you are planning for the years work in Language arts classes, for example, you could in your annual draft, plan to start the year with poetry, move onto the novel genre in the second semester, the drama genre in the third semester, and so on.
Once you have a broad outline of the skills and sub-skills that you are going to teach, you can then move to thematic units. If you are aiming for a cross-curricular approach in your home classroom then a summary of themes should be added to your annual and quarterly planner. These themes will obviously cross over all of your subject year plans. If you are beginning with a broad theme such as the environment, then your resources for all subjects would be based on environment issues. Quite simply then, your English comprehensions and written work would be related to an aspect or aspects of the environment. In the mathematics class, your examples would be based on the environment, and so on.
