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.
Once you have a broad outline for the year, you would add sub-skills which should be covered each semester. You could in the language arts divide the various punctuation marks and their rules up over four semesters. Your language sub skills such as sentence types would have to be covered with the introduction of a statement requiring a period; a question which must take a question mark and so on. You could progressively add to your planning so that by the last semester you will move to the rules for direct and indirect speech, once all the necessary punctuation marks have been covered.
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.
