Dd is in Reception and has said that they practise writing the letters (that the teacher illustrates on the board) either on the carpet or in the air.
I used to teach in Year 1 and had children coming up to me (state school) being able to write in full sentences with capitals and full stops. Even the middle ability children were able to write a couple of sentences about themselves.
DD brings home some cursive writing letter sheets but they didn't actually write them out at all. She is pretty accurate as to what goes on workwise at school.
Have expectations changed as to what Reception children do? I haven't taught Year 1 for about 7 years.
