my 11yr old son has dyspraxia and mild dyslexia,
starting high school is a big thing for any child but even more so for, a dyspraxic child because of their lack of organisational skills, you mentioned she was statemented,
have you had a meeting with the senco at her new school to discuss what help they will put in place for her and have they drawn up an I E P, all the teachers she has should be aware of her dufficulties and set the homework accordingly,
if this isn't the case then you need to contact the school and tell them she isn't coping with the homework,
regarding her not wanting to join in that is quite normal for a dyspraxic child because they suffer from low self esteem and will often avoid these situatuations because they get laughed at or teased, find out if the school runs sensory sessions they really do help
is there a Dyspraxia support group in your area, it may help your daughter to meet other children in the same situation,
and it would help you if you had someone who understands to talk to,
has she never questioned why she gets help in school?
my son was a completely different child when he was diagnosed it made him feel better about himself he understood why he couldn't tie his shoe laces or throw and catch properly but it hasn't stopped him learning the saxophone, the medication will be for the ADD, but all children with dyspraxia have a short attention span.
