An important part of planning your KS2 curriculum is being able to share the rationale with pupils and parents. So often the order in which history topics, (beyond chronological order for British topics) are tackled must seem quite random. Showing explicitly what the learning journey ahead looks like and how it was conceived is an important part of bringing a coherence to your planning. As the principal audience is the pupils themselves, you will need to keep this fairly clear and simple so don’t clog it up with too much detail that belongs elsewhere.
So this forms part of a suite of key planning documents, central among which is the long-term skills/concept guide which shows not only where the emphasis lies within each topic ( e.g. interpretations, cause, change) but also where the explicit teaching of concepts is plotted across the key stage. This is also the starting point for building progression into the learning.
