The first document is a summary of the whole narrative, broken into 5x 2 page chunks. The idea would be to give one summary to the students at the beginning of each of the 5 units and for them to learn it inside out. That way they can pin their developing knowledge to this core narrative.
The second document is an overview task which would work for any of the C19th America GCSEs. Here pupils are asked to pitch and storyboard a film which best tells the story of the making of America. This would be a good revision exercise.
I have added both of these to the overall index HERE and you can find all files in via the Teaching Resources link at the top of the blog bar (to the right).
