Go Shopping! : You can cater this to all different ages. For young children, you can do a 'mock shop' and let them pretend to go shopping in a pretend store (your kitchen). Label certain items with easy to read prices and print some pretend money for them to shop with! For older children, you can let them help you in the actual grocery store with a specific shopping list. You can even set specific spending limits and give a specific amount of items and let them determine what they can afford, etc.

Trading is an art. By being aware of your intuition and your feelings, you may find that you are able to trade in unique and different ways. The only way to discover that is by documenting it.

Through the accumulation of 10, 30, or 100 journal entries, you are able to reasonably determine how well you are doing.
