Wow.
Kids this age can help with so many things.
Folding laundry and putting it away. Towels and wash rags are super easy to fold. Underwear and folding their own socks and putting them away is also easy.
Vacuuming
Dusting
Separating recyclables. Have a bin for plastic and paper.
Watering and weeding plants. Little kids love refillable water spout cans. Just be sure to teach them the difference between weeds, grass, and plant sprouts. This time of year is a perfect time to let them have a spot in the yard for planting pumpkin seeds. They basically grow on accident so just a little dirt and some water and you'll have pumpkins next year.
Let them make their own beds. Give them a sticker for keeping their shoes neat and getting their clothes ready for the next day.
Even at 5 and 3, my kids loved showers. I gave them a cup and a scrubby pad and they would have fun "washing" the shower. It didn't have to be perfect, but as they got older, it just became a habit and the shower was always rinsed out. I gave them a squeegee and let them have at it.
Setting and clearing the table is another great chore.
I never had a sticker chart. My kids just always loved to help. My son was fascinated with the vacuum. He had his own little apron, broom, and dust pan. He loved loading the dishwasher. His sister was older, so she would unload after I'd put the sharp items away.
Kids really do love to help and if yours are inspired by a chart, ask them what kinds of things they would like to do to help. Go from there.
My son is now 17 and a fabulous cook. He can literally cook or bake anything due to the years I allowed him to help in the kitchen. Being raised by a single mom, he knows how to sew, work on auto engines, do his own laundry. I think chores help kids know how to function within a family and beyond.
I, personally, didn't offer rewards, but I had plenty of friends who would hire my kids for their responsibility and work ethic. They paid them for their efforts.
When it came to our home, it was just a matter of us all chipping in and leaving us more time for fun things. I always worked full time, so everything we could get done as a team left us more time to do other stuff.
When my daughter hit her teen years, she thought helping at home sucked. But, my son....he never strayed off the path of helping being the best for everyone. He, to this day, never does it for a reward.
All kids are different and whatever you can find that works for your kids....
Go for it!!
