Chore charts really do work with all ages. Make one up on your computer so you can make it fit your lifestyle, and you can personalize it. Let them pick the colors, or even put fun pictures on it. They can be easily printed off, and thrown away at the end of the week. Hang it where your kids can reach it, and let them check off their daily chores. It’s a good reference for you to see what they’re doing/not doing, and gives them a great sense of accomplishment. If they can scribble with a crayon, they’re old enough to start!
