As a parent you have the responsibility to help your children understand money. But first you will need to understand your own attitude towards money, and make sure to practise what you teach.

Ask yourself what things that cost money are the most important to you. Also ask yourself what financial goals do you have for yourself and your family this year, in five years, and so on?

Take a minute to write down a list. Below are some ideas to get you started. There’s no right or wrong here. This exercise is just to help you grasp what money means to you so that you can help your children understand your values.

◆ Home

◆ Household expenses

◆ Education

◆ Recreation, entertainment

◆ Savings

◆ Charitable contributions

You can start discussing money when your children are as young as three years old. The best time to teach a child anything is when he or she shows an interest. So he prepared to start talking about money when your child starts asking you to buy candy or toys.

Begin by showing how money is exchanged for items or services. Show your children how money works by allowing them to buy something, such as a toy or a book.

Be open and honest, and explain to your children why they can or cannot have certain items. If you must say no to a child’s request to spend money, you might say, “You have enough toy trucks now.” Or, if the request is for multiple items, “You have a choice to make, between this toy and that one.”

You can start explaining the bigger picture once your children understand the basic function of money. Show an older child how money is used to provide for the whole family.
