Chores

My children, (see above) will be 3 and 5 this summer.  They often help me and my husband with chores around the house, but we do not have a formal system of tracking chores.  The only thing that they have to do every day is put their clothes in the hamper and clean up the toys.  I feel that it is time to help them begin to learn responsibility.  I am currently working on a list of chores that we feel would be appropriate for each of them.  So far, this is my list:

• Put their clothes in the hamper - morning & night
• Put away their toys 
• Set the table for supper (with assistance)
• Put cans in the recycling trash can
• Help me with the laundry - spraying clothes with spray n wash and putting clothes in washer and dryer
• Water flowers (they just think this is fun - definitely not a chore)
• Dust with assistance

I am planning on setting up some type of chore chart with pictures and putting stickers on the chart when a chore is completed.  Do you have any other suggestions for chores for young children?
