The Lemonade Stand Game is a business simulation laboratory for practicing sales and manufacturing forecasting. Demand fluctuations are tied directly to weather variations. Rudimentary market feedback, about the portions of ice, lemon and sugar, covers customer service basics. A relatively high random spoilage factor requires a tight focus on inventory control.

An optimal inventory target for the perishable ingredients is in the range of 1.2 - 1.5 days. The combination of chaotic weather and spoilage factors provides the player with an opportunity to take high-risk runs at a high score. On the other hand, using a lower inventory factor often results in a more consistently profitable business over multiple games. Assets should be carried as cash or cups, primarily cash. It is quite possible to go belly-up in any given session without careful attention to all of these factors.

Very basic primary school math skills are all that's required. If a child can add, subtract, multiply and divide they'll have fun running their own lemonade stand. When they first play the game, a player might test wide variations of ingredient quantities, ranging over various multiples of two. For example, if 8 and 16 unit tests produce better feedback and profits than four, the value to test in the next iteration is 12. Most players recognize the patterns and relationships between the various factors fairly quickly, and have a lot of fun zeroing in on a good series of runs.
