There are a lot of ways to present chores to kids. They can be tied to allowance or to other privileges, and this is fairly common. But I would like to propose a different approach.
I grew up under a straight system of chores for allowance, and given my comic book habit this worked nicely for me. However, this arrangement encouraged me to cultivate a somewhat mercenary attitude: I failed to see the use of raking and bagging leaves, for example, other than as a source of income; and if I did not have plans for the money my enthusiasm for the job was…lacking.
More useful, though, was my weekly job of mowing the lawn for my grandparents: the expectations were clear, and the wage ($10 per job) allowed me to steadily accumulate funds for movies and role-playing game modules. More importantly, it prepared me for the exchange of labor for pay that goes into any future job, particularly of the sort available to teenagers. I was expected to show up each Saturday morning, and my grandfather was good enough to inform me of when I needed to do the job with a different emphasis or with increased vigor.
As a result of these experiences, I have come to see the use in framing a job as a job and chores as something else entirely.
In my house chores are presented simply as expectations: they are what need to happen in order for the home to run smoothly. There is a place for everyone to chip in, and we emphasize the importance of each chore in our day-to-day home life. It is important for chores to be age-appropriate, and there are a number of resources that can help ensure this. I like this list put out by Montessori educators, and it has served as a useful guide.
Recently, inspired by a Nurturing Parenting training, I decided to formalize the process. I bought a whiteboard (though a piece of paper, or any of a number of online templates, would serve as nicely) and created a chart, with chores listed down the left-hand column and days of the week along the top (no chores on Sunday, as we go to Church in the morning). I found a set of magnets and labeled them with names, with two magnets (two daily chores) per child. I rotate them daily so that they are performing different tasks each time—their preference—and place them according to age. I allow the girls to write and/or illustrate each chore.
Here is the current list of chores for our household:
Trash patrol (gather bits of paper and other detritus and put in trash bin)
Laundry patrol (gather clothes and put them in hamper)
Put away dishes
Sort and put away clean laundry
Library (gather and shelve books—we have a lot of books)
Take out trash
Clean bathroom (Scrub sink and bathtub, tidy and clear floor)
Making beds is a daily chore for everyone.
Sometimes we assign “big girl” chores to the little ones with the expectation that an older sibling or adult will assist them. This helps to familiarize them with tasks for which they are not yet ready.
We have been using this system for a month now, and it seems to be working. The kids are more willing to do their part when they see that it is consistent and part of an organized system. I expect that changes will continue to be made, which is why I use a whiteboard and dry-erase markers.
This is not the only way to do it, and it may not be ideal for your family. I encourage you to explore resources, talk to other parents, and come up with something that suits you.
