Have you ever run a lemonade stand? It is a great way to start learning about running a business and you get to use real life MATH! Here is a recipe to make 1 batch of lemonade.
1 Cup Lemon juice (use 5-6 lemons)
¾ Cup Sugar
1 Cup Ice
4 Cups Water
The recipe makes 48 ounces (eight servings 6 oz. each).
