Hi Year 11,
as the theme is now decided and we know some of the dance pieces involved - perhaps you could start with a basic structure and say which section each dance represents.
Then we will have an idea of which sections still need a piece creating for.
As well as your Y11 dances - Y13 have 3 pieces, Year 2 will have 2 pieces and Y10 a possible 2 or 3 pieces.
Lots of hard work ahead - good luck
Mrs G
