Help with sign Language for Learning Disabled

Hi All,

I would appreciate if you can send me a link where I can learn sign language for those with learning difficulties. I work for a special school in u.k. and find it difficult to communicate with students who use ‘only’ sign language. With observations I have learnt simple greetings like ‘good morning’, ‘good morning’, ‘toilet’, ‘sitting’, ‘upset’. I am new to this and hence need help.

Thanks in Advance
