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.
Step four should take the form of an evaluation of the lessons successes and shortcomings. While the lesson is still fresh in your mind, jot down your observations, note difficulties and areas which will need further clarification the next day. The true value of lesson plans is that one can check at a glance if all the necessary resources are in place for the day or unit or week ahead. Lesson plans must make provision for a variety of activities. Take your childs attention span into account when planning lessons. For example you could begin with a teacher tell approach where you keep explanations brief and repetitive, then pose questions, then move to a pen and paper activity. Thereafter you could move to a computer based task and finish with a worksheet which should assess whether you child has grasped the concept covered.
