Mathalicious: Crop and Trade

Which crops should farmers grow?

When a farmer wants to have more than one crop, she has an option: grow multiple crops herself, or specialize in one crop and then trade. Which option is better, and how do producers decide whether to diversify in production, or specialize and trade?

In this lesson, students use linear relationships and proportional reasoning to explore comparative advantage and the risks and benefits of trade.
