There are some household chores that almost anyone can do. And children, like older people, like to feel that they are useful. With proper training or guidance, children can do age-appropriate tasks and contribute to running the household. In some families, the successful completion of chores is a paid activity. In other families, chores are just expected of all family members. Still others use a mixed model, some tasks are required, while others, extra tasks, can earn the "worker" extra cash.
