This game teaches ratio and proportion by having learners make "salads" that combine three types of beans in different combinations. The recipes are written as word problems, such as "2 Lima beans/Twice as many Red beans as Lima beans/ 10 beans in all." The introduction page explains ratio and proportion, and connects the idea of proportion to algebra. This activity explicitly encourages trial and error. There are eight different recipes, and an extension to create new salads and write instructions for someone else.
