This is a fun activity for middle and early high school. Ratio and Proportion is one of the most powerful tools in algebra and geometry. In this activity, students are given a delicious and decadent "Stop Your Heart Brownie" recipe. They must analyze the recipe and determine the total calorie and fat content to help out the math-challenged Chef Bobby Mathematique so that he can accurately let his patrons know what they are consuming.
There are two lessons - one gives the basic data on the ingredients. In the other, students research the data for themselves. Once they have determined the total fat and calorie count, they calculate the per-serving totals for various serving sizes. Finally, they make a report to give to Chef Bobby, including real-life diagram of the various sizes and the number of servings per baking sheet.
By the way - this recipe is AWESOME and a favorite of my family and friends!! Enjoy!
