Minyanland
Another gem from Kevin Jarrett! It’s called Minyanland.com and it’s totally free!

From the Minyanland site:
We created MinyanLand as a platform to entertain and educate a young generation so they understand the concept of a market and the basics of economics and finance on a real world level. The economic system of MinyanLand mimics the real-life pricing of general goods and services. As players participate in the system, their actions will affect the overall MinyanLand economy. This is how they will learn. To keep the economy stabilized, for instance, players must stay healthy by eating on a regular basis. MinyanLand will also offer incentives to encourage such behavior as charitable giving.
K evin says:
Kids work jobs that require them to use, among other things, math and reasoning skills, they learn about the value of money and the concept of investments and they interact in immersive 2D spaces that combine nifty graphics with recorded, realistic environmental sounds that make the experience incredibly lifelike.

Internet safety is paramount at Minyanland, and the chat system (partially shown above) helps ensure that messaging is limited to the context of the game and that no personally-identifiable information is shared.
There is no mention of a suitable age group for this game so maybe one of you could investigate it during the rest of the school holidays and leave a comment here as to what age group you would suggest.
