For this activity, work together as a subject department. Take the syllabus for the first term you teach students when they join your school (this will usually be at age 11/12, although in some subjects it might be a little later).

Identify the “Big Ideas” you feel you are teaching in this first term. There may be just one, perhaps two or three, but not more than that. Then briefly write out the subcategories of the Big Idea concept(s) you have identified.

The purpose of this activity is for you to engage with the structure of your subject. You will find plenty of Internet information if you wish to deepen your enquiries on this theme. Keep the lists you have drawn up, as they will be needed in the next activity.
