Money and time are challenging concepts for kids; both are abstract and both require lots and lots of practice before kids get them. To help kids learn about the value of money, you can try having kids take over your next shopping trip. It’ll help them understand what things cost, practice their subtraction and make them feel like big kids.
Just make sure you start with a list or who knows what will end up inside the basket. I can see it piled high with candy bars now. We chose the Roasted Chicken recipe from Farm to Table Family. You can also include the kids in picking out the recipe. It might make them even more likely to eat dinner that night.
The added benefit of having the kids shop, is that they get a chance to work on their social skills. They have to ask for things in a clear way, make eye contact and interact with the vendors in order to make their purchase. One of my kids can be quite timid, so this was a good chance for her to gain some confidence interacting with adults.
Oh and because kids grumble (one of my kids really hates shopping), try building in an incentive—if they have money left over, they can buy a treat. That’s the part kids love best!
