I did some googling on age appropriate chores. A friend asked me to make a chart for her Daughter- so I have a chart for 6/7 year old's, as well as for my boys. I included some of our goals for learning as well as daily tasks. For example "read a story with a parent" we read at nighttime often but this is to encourage extra time reading together. You could even customize this for behavioral goals as well.
Our rules are that all items must be completed to earn the sticker for the day (this is more for K, J is a bit little for it yet). We're then deciding as a family on a monthly reward.
