This lesson is a real world activity to be used as the last lesson of the unit. Students use a recipe to adjust the ingredients based on a new serving size. Students use their understanding of ratios and proportions to solve the equations and come up with the new serving size. This activity allows students to use what they have learned about ratios and proportions from the previous lessons and apply them to a real world problem.
Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, “The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak.” “For every vote candidate A received, candidate C received nearly three votes.”
