children doesn't need to know about currency,but teenagers does,and i think there's so many explanation video in youtube so don't wasting effort wasting your time when you can just give them about the link of video so they can learn from it,whether they will be interested or not,it's definitely depend on them
Yeh, your right.. Children doesn't need to know about the currency, and yet to trade.. Because they are still too much young to know more about it. The best they can still do is on to focus on their studies. But the teenagers does. Yes they can, because of their age can understand all about of what you can discuss on them. Teen-agers must have more mind-set to understand about it all.. Than the children's can not yet.
