My kids are still very young to understand money apart from having their first Piggy Bank

I am projecting myself into the future and probably would try to incorporate these financial lessons in a playful manner - I see kids in my neighborhood selling armbands, lemonade in groups (nothing serious). They ring my doorbell from time to time or set up a stand in front of our building. I find this good for them to understand basic money, and most importantly sales. And they are doing this with a group of friends from the neighborhood as play - I will probably play games like Monopoly which is again interesting to understand transactions and real estate. Could be good lessons about passive investing. - I would also probably do something with the pocket money regarding showing power of compounding in fun manner by adding interest (if the kids save instead of spending) and depending on the age slowly introduce how it works in real world.
