I expect/need my kids (5 and 1) to do their part. There are no set chores per se, but I expect them take care of their messes. You take off your clothes and put them in the hamper. After you're done eating, put your plate in the sink. When play time is over, put your toys away. My 5 yr old has always been independent, responsible, and pretty self sufficient--I have to tell her not to do several things (please don't cook your own food, give yourself medication, take care of your sister).
My parenting and teaching style is typically to expect a lot, and the children have yet to disappoint me.
Blame it on the cell phone...
