I know, you already taught them their colors years ago. But it's time to review. Have them sort their laundry by color. Whites, pastels, light gray and white background prints will go in one pile. Deep colored clothes – black, red, navy, brown, dark gray – go in another pile.
Now, have them sort each pile one more time by type of fabric. For instance, in the pile of whites separate towels and sheets from apparel. In the dark colors, separate t-shirts and jeans from lighter weight items like blouses and dress shirts. Washing by fabric type allows you to use different water temperatures and keeps drying cycles simple.
Once they've mastered this skill, you can share that if there are not enough items to make up a full machine load of each type and you are in a hurry, you can wash all of each color together. Just be sure to choose cold water and the machine cycle to fit the size of the load and the most delicate items. But, you may want to save that information until they get a little more experienced.
Remind them of to check that all pockets are empty – even tissues and paper. Remove any accessories such as belts and jewelry. Close all zippers and buttons.
