Im not suggesting she's gifted...but she is DEFINATELY pretending to be less able.
She's always done this...she is in year 3...and she has just begun a new school but she dd this in her last school.
She writes quite neatly when she's messing around in her room...little pictures and notes...as soon as she has a bit of homework she writes, draws and colours like a baby and it can take more than an our to get her to complete a small and simple task and then it looks aas though it were done by a four year old. 
The school she was in was a small prep and she had lots of attention ...they just said she lacked concentration...she had a lot of homework there...a piece every night in addition to reading, here she is only having one piece plus reading and weekly spellings.
She's not so bad when it comes to reading and spelling pactice..but anything involving putting pen to paper which isn't her own ideaand it turns into a massive battles.
Her grades were 2bs and a 3 in science....she had a 2c for writing. but she CAN write better than she does at school...I see evidence al the time!
