Financial literacy has been on a wide range of effectiveness to the society at large and it's impact on our kids at a tender age will make it more suitable and beneficial to them and the society, having kids with a 100% prospect on finance will go along way of reducing financial instability and let them understand and manage personal finances effectively, making informed decisions about earning, saving, investing, and spending money.
And how do we execute that it's at this early stage of their lives ranging from 7 and above.
Actually with the nature in which the economy of the world is falling really requires us to set a good financial path for our children by making informed financial decisions for them at a very tender age but the age range of 7 years you made mention of is rather too early for a child to know about how to make money because I have seen children that their parents exposed to business ideas at a very tender age and this children where unable to further their education because they felt it was a waste of time going to the school and they grew up with the mentality that everything about life is all about money and they ignored seeking for educational exposure and became full time business people.
There is need for a child to graduate through school before being exposed on how to make money of their own because at that very tender age, whichever thing you expose to them they will take it up till they are grown and even though they can earn while studying but in most cases it becomes a distraction to them in their academic pursuit, Everything about life shouldn't be about making money but the only thing I can say is that parents should learn how to save money for their children, possibly open a kiddies account for them so that when they have grown to a certain age where they can take full responsibility of their actions and inactions then they can be exposed on the best financial decisions they can take with the amount already saved for them it will go a long way in the success building of that child.
