It takes more than words to teach a kid how to ride a bike. Not even the clearest explanation of balance or a dazzling visual aid about proper seat height will help when those handlebars start to wobble. The only way a child can get it is to step on the pedals and practice. Learning how to save money isn't much different. Instead of merely telling your son or daughter that saving is important, give him or her a hands-on experience. Just as you'd start your child on a bike with training wheels, consider opening a jointly owned savings account to teach good money habits.
