You've Got a Deal!

About this game:

When you enter into a contract, you don’t want to leave any money on the table. You have to understand the terms of the deal, to know what you are entitled to, and whether or not it is better to pursue one opportunity or another. In this game teams take turns drawing two tokens to represent a ratio. The teams not only get to all of the occurrences of the ratio, but under the terms of the deal, they get to capture all tokens which represent equivalent fractions. For example if they drew a 4 and a 7 the team could collect all the occurrences of 4:7 and 8:14 and 12:21 and so on because they are equivalent fractions.

Tips & Tricks:

If you want to emphasize probability, allow teams to select at the same time and then trade if desired or trade one of their tokens for another from the treasure trove.
