     Many children first learn the value of money by receiving an allowance (零用钱). The purpose is to let

children learn from experience at an age when financial mistakes are not very costly.

     The amount of money that parents give to children to spend as they wish differs from family to family.

Timing is another consideration. Some children get a weekly allowance. Others get a monthly allowance.

     In any case, parents should make clear what, if anything, the child is expected to pay for with the money.

     At first, young children may spend all of their allowance soon after they receive it. If they do this, they

will learn the hard way that spending must be done with a budget (预算). Parents are usually advised not to

offer more money until the next allowance.

     The object is to show young people that a budget demands choices between spending and saving. Older

children may be responsible enough to save money for larger costs, like clothing or electronics.

     Many people who have written on the subject of allowance say it is not a good idea to pay your child for

work around the home. These jobs are a normal part of family life.

     Paying children to do extra work around the house, however, can be useful. It can even provide an

understanding of how a business works.

     Allowances give children a chance to experience the three things they can do with money. They can share

it in the form of gifts or giving it to a good cause. They can spend it by buying things they want. Or they can

save it.
