Monopoly for Preschoolers

My kids like Monopoly. But they’re too young to do addition. And the biggest hassle of that game is always making change. So my wife and I came up with some alternate rules to facilitate playing as a family without driving any one member of it insane.

• All bills count for the same amount: $1. There are enough $1 bills for each person to start with 10 of them; you can add $10s in if you need more.
• All money values are single digit values: take the maximum of $1 or the hundreds digit specified. (i.e. Math.Max(1, originalValue % 100).) So a property listed at $280 would be worth $2. A fine of $75 would cost $1.
• Instead of needing a monopoly to build houses, you can build a house when you land on a property you already own. It costs $1 to build a house. If you land on a property with a house, you can add another for $1. Likewise, if you have four houses, you can replace them with a hotel for an additional $1.
• If you land on a property owned by someone else, you pay that person $1, plus $1 for each additional house (or a total of $6 if there’s a hotel).
