just had a row with ds2's teacher
he's 6 and in Y2, in the top reading group and very capable, although he is not keen on reading and writing and is apt to be slapdash
he reads at home with me and writes for a purpose "insulting notes to his brother, nice notes to me etc 
and I work in early years so I have a reasonable grasp of where he is
two of the children in his reading group have been having harder reading books because teacher thinks they are at a different level - I think the books ds2 gets are pitifully easy and dull, but I haven't questioned it much (did mention it at parents evening but didn't push it)
today though his spellings were "have", "out", "with", "some" etc - he could spell those when he was 4 fgs
the two top ones in his group had "eventually", "different", "heard" etc
I asked the teacher whether she was sure these were the right spellings as they look very like the ones he had in Reception
she said the whole class aprt from the top 2 had the same words, apart from the 4 lowest who had the same words but only 4 of them
she showed me the long test they did last week where my ds2 had spelled "were" as "wur"
If I were his teacher I would have kicked him up the proverbial arse and made him do it again - she knows damn well he can do that level of work standing on his head.
I WILL talk to him about being lazy, but honestly I am fuming that the teacher isn't making any effort to get anything out of him, I feel that she has "picked" the two top children in the group and sod the rest
