Do a family session of cleaning at a set time each day. Try to give everyone a different task each day and make sure those that complain the loudest still get the unpopular tasks regardless of thier complaints. Include the once in a blue moon tasks as well as the everyday sweeping.
Have a feed yourself week. Kids have to create abalanced menu, shop for it and cook for themselves, as if living on thier own. Variations on this include having a low budget or doing batch cooking and freezing the excess.
Pocket money for chores. If kids cooperate on the daily family cleaning sessions, they get a 'wage'. They must save a certain percentage into a bank account, they must buy thier own toiletries, 4 times a year they must give to charity (can be as little as 10p in our house, but just so they learn it is an option).
Monthly clothing allowance. Give them a list of minimal clothing they must have eg. 5 t-shirts (in good repair), 5 trousers, 2 jumpers etc... Then it is up to them to chose, buy and maintain thier clothes. They can still get special items given to them for Birthdays/Christmas on top of thier allowance.
I find shoes a difficult item to include because they are forever growing out of them and they are so expensive. The child might prefer to spend thier allowance on a special football shirt and be crippling thier toes as a consequence.
A proud parent chart. This is kind of a reward chart but it is not asking for any particular behaviour. Any time you are proud of them for doing something small (comforting a sibling, controlling thier temper in a certain situation, achieving a good grade. Then the marker goes up 1. This marker must NEVER EVER go down. It is not a chart to let them see how bad they have been and it must certainly not be used as a punishment. It is a count of how many times you almost cried with pride. - It can take a while to reach the top and different children progress at different rates obviously. Reaching the top should get them a special little pressie.
