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 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.
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.
