Lots of people have mentioned Scratch Jnr, which is a great place to start, but don't stop there. The full version of Scratch is fantastic. My daughter (9) and son (11) both enjoy it, though my son is really into it. They both particularly like the fact that you can remix other people's code - it's a great way to get started.
