[senco-forum] specific language difficulty

We have a 10 year old boy with specific language difficulty/impairment  -
average non verbal IQ, but  poor language ability. He has poor phonological
processing. I've just read a research paper of Maggie Snowlings about the
differences between SLI and dyslexia, and how they should be looked upon as
different things but it didn't go into intervention. Do any of you teach
children with specific language impairments and if so have you found
anything particularly useful - this boy has a reading age of about 7 years.
