Financial Literacy with Preschoolers

We are currently homeschooling and my 4 and 3 year olds know that something needs to be on our budget when we go to the grocery story or we don't buy it. We can have a conversation about what they want to buy and how much money we have. We can look at what it would take for them earn the money or if it could be better to save it etc. There are so many real life applications here!
