Agressive behaviour - ways to shape and change

Dear all,

I am new to the forum so can I just say a quick 'hello' and thanks for such a wonderful discussion forum.

So to get to business, I care for a number of children, aged between 10 -15, who are present on the spectrum. My latest challenge is to find ways to challenge and change angry behaviour. This is typically set off by issues which are common in any children, such as a change to routine etc. I have completed a reflective chart with the children and am now looking at ways to suggest changes. I know this is hard for children on the spectrum and I was just wondering if anyone has any suggestions? For example, do behaviour charts work etc?

Huge thanks to all!
