My dd has always loved what we call the "chocolate game"
Probably best to do two games simultaneously as ten kids too many.
Get huge choccy bar and place on tray in middle of circle of seated kids.
Put gloves ,scarf,hat,knife and fork ,oh and a dice,on the tray.
When a six is rolled that child has to don the clothes and try to cut open the chocolate before another child rolls a six and tales over.
I don't know whether six is too young,test with your ds first,but all kids love this and get really excited.
Winner that opens bar gets to take it home,or share
A mexican pinata is always good aswell
