MPA map with nRich clarification

I have adapted the MPA map from the standards site so that the phrases used are a little more understandable and so that we can find exemplification of each one. I have done this by using the nRich process mapping spreadsheet, taking their titles from each of the MPA categories and allocating these to the phrases used on the original MPA map. So, if you look at the adapted map I have made at http://www.wiltshire-ast.co.uk/media/maths-documents/index.php you will see that each "node" refers to the phrases used on the nRich process mapping spreadsheet (http://nrich.maths.org/curriculum) and this spreadsheet has hyperlinks to activities that they say cover that skill. Hope that makes sense.
