Free Labor

In our house our girls are expected to do the following things:

1) Set their place at the table- get their own plates, cups, bowls for snacks, meals, drinks
2) Put their dishes in the sink after dinner (we help Molly with hers to reduce mess)
3) Let Max out and in when asked
4) when they walk in the door put their coat and shoes in the foyer (slowly moving to actually putting them IN the shoe holder, but one step at a time)
5) Putting their dirty clothes in a hamper
6) Helping clean their rooms and their toys

There are extra things that they are asked to do that results in a reward (we try to make sure the reward is not used to get them to do it, but offered when they do as asked without fighting it or telling their sister to do it).

Do you have tips and tricks for developing good habits in your household?
Do you have other chores you have your kids do?
How do you reward?
