Started teaching my son when he was about 6. He took things out of the washer and put them in the dryer, cleaned the lint trap(which he loved!) and started the dryer. He's 11 now and can do any laundry. We sort into four piles-delicate which normally includes whites, towels-socks, jeans, and DH's work clothes.

Washing included sorting, using the machines, and putting it away, even though that might mean pulling clothes out of the basket part of the week to wear. I don't much care as long as I don't have to deal with the clothes.
