Step one: fix subject, level and lesson length
Begin by choosing one subject, one level and one lesson length, for example a forty-five minute lesson on fractions for upper primary classes. Narrow scope matters because a template that tries to fit every class ends up vague. Write a single sentence naming who the page is for and what a teacher will walk away with. Decide whether the page will be printable, editable or both, and note the common constraints in that setting, such as mixed ability groups, limited devices or a short preparation window. These choices shape every later section.

Step two: lay out the sections in teaching order
Arrange the template in the order a lesson actually unfolds. In the fractions example, start with a learning objective written in plain words, then a three minute warm-up question, a worked demonstration, guided practice, independent tasks at two difficulty levels, and an exit check of two questions. Give each section a suggested time and a short prompt, such as what the teacher says or asks. Leave visible blank space for materials, grouping and adjustments. Keep headings consistent so a teacher who learns one page can read the next without effort.

Step three: test, trim and add a worked sample
Ask a teacher to fill the template for a real upcoming lesson and time how long it takes. Watch where they hesitate, skip a box or rewrite a prompt, then trim or reword those parts. Add one completed sample, such as a finished fractions lesson, so newcomers see the expected level of detail. Finish with a short revision note describing what changed and why. Only after one subject page works smoothly should you copy its structure to a second subject, keeping the same layout so the collection feels coherent.
