Following on from a couple of other threads, I've now asked for a meeting with dd's teacher & the HT (who is also the school SENCO).
I'd like to go along with some suggestions of things that might help dd stay focussed on her work.
My list so far (thank you Seeline and Mrz!) is below, but I'd love any other ideas to add to it :)
No distraction area - perhaps sitting on her own if possible when there is a longer piece of written work to be done.
Using some sort of timer to keep track of progress
More frequent verbal reminders of how long is left to complete something
If the task is to do a certain number of things, writing a list of the numbers and crossing one off each time she completes one
Using a white board (or a piece of rough paper) to quickly jot down initial ideas - even single words help
Using a dictaphone to quickly record ideas verbally and then listening back to it whilst writing down in 'English'!
I do realise this isn't magically going to help dd be able to write, but I think that it might help a bit, and also mean that she gets in less trouble (she is very bad at staying 'on task' with things she can't do).
