That's a wonderful initiative to start teaching financial literacy early! One effective method I've used is the "three jars" system where each jar represents saving, spending, and sharing. It visually shows them how to allocate their money and teaches them about budgeting and philanthropy from a young age.

For something a bit more interactive, board games like Monopoly or The Game of Life can make learning about money management fun and engaging. They get to practice handling money, making financial decisions, and understanding the consequences in a playful environment.
