My six year old is in yr one and not very long ago was given a certificate saying he'd 'got' level one in writing. Was a bit confused as a week or two before that his teacher said at parents eve he was around 2c in writing. He writes constantly at home - stories, lists and does beautiful cursive writing (much much better than mine!). Uses question marks, commas, colons, exclamation marks, speech marks and apostrophes correctly, almost always and full stops and capital letters are always correct. I think content of his writing is a bit immature, not surprisingly, but here's a sample which is v typical. I'd be interested to know what people think...
There was once a monster called Mini Monster, he was very small and very cute.
One day Mini Monster disided to go for a walk so he did go for a walk!
Then he saw a pie factry, it had lots of pies so he went up to the pie factry and ate all the pies! And then after Mini Monster had aten all the pies, Mini Monster went home and went to bed.
There are pages and pages like this lying around the house but I won't go on.
