A weekly lesson plan is a map, not a script. It shows which subject goes where, how much time each one gets, and where the gaps are, before the week starts. Without a map, one subject quietly eats two extra periods and another gets squeezed into Friday afternoon. This planner builds a balanced week from your subject list, so you can see the whole shape at a glance and fix it while it is still easy to change.
The method is rotation. List your subjects in order, set how many periods each day holds, and the tool fills the week from the top of the list, wrapping back to the start when it runs out. With five subjects and five periods a day, each subject appears once a day. With four subjects and five periods, the first subject appears twice on day one, then the rotation shifts, so no subject is always last. Over a full week, the counts stay close, and the planner shows them.
Here is a worked example. A teacher lists Maths, Reading, Science, Art and Sport, sets 5 days, 5 periods per day, and 45 minutes per period. The week holds 25 periods, which is 1,125 minutes, or 18 hours and 45 minutes of teaching time. Each subject gets exactly 5 periods, which is 225 minutes. If the teacher adds a sixth subject, the counts spread to 4 or 5 periods each, and the planner shows that at once, so the trade-off is visible.
Total time is the number most plans forget. A week plan that looks neat on paper can still hide a short week, because a school trip or an assembly removes periods. By showing total minutes and hours, the tool lets you compare weeks fairly. If one week has 1,125 minutes and the next has only 900, you know the second week must drop something, not squeeze everything in faster.
Order matters, and you control it. Put the subjects that need fresh minds first in your list, and they will land early in the rotation more often. Put practical subjects later if your rooms are free then. The rotation is a starting point, not a rule: swap two cells in your head, or reorder the list and generate again, until the week feels right for your class and your rooms.
A plan also needs room for real life. Assemblies, trips, tests, and bad weather will break any perfect week, and that is normal. The value of a written plan is that you can see what was lost and what still needs covering, instead of discovering the gap on Friday. Keep the generated plan as a base, and note changes beside it during the week.
There are clear limits here. This planner does not know your curriculum, your room bookings, or your school rules, and it cannot judge whether a subject needs more time this week. It balances counts, and you supply the judgement. A fair rotation is a good start, but a thoughtful teacher still moves subjects around for tests, projects, and the needs of the class.
You can use this tool in several ways. Build a standard week once, then reuse the same subject list with small changes each week. Try a 4 day week after a holiday and see how the counts shift. Copy the plan into a document or download it, and share it with a teaching assistant or a cover teacher. Keep the plan where you can see it during the week, and check it each morning, so small changes stay visible and no subject quietly disappears from the week. In short, it turns a blank week into a balanced, readable plan in a minute.
