One little thing it says in the framework for GPS (key Stage 1) that strikes me as being odd: 4.4.4 The use of the serial comma The mark will not be awarded if a serial comma is used in a list of single items, e.g. We bought apples, cheese, and milk. Who has decided that the "Oxford" comma (so called because it is the style of the OUP) is incorrect? Has this been published "gov think" in the past? Perhaps it isn't an oddity if that's what you've been trained to think and what you've had to teach but it's still a popular style in the UK and who's to say it's wrong?
