The central focus of this learning segment is to provide an opportunity for students to model and solve a real-world mathematical problem related to the volume of different 3-D shapes. In this lesson, students will use the formulas for the volume of a sphere and volume of a cylinder to help them answer the guiding question, “How many meatballs will it take to completely fill this plastic container with sauce?” Students will then have an opportunity to put theory into practice by actually modeling the problem and testing their answers to see if they were correct. As students work to solve the problem they will provide written and oral responses to justify their work and through their responses, it is expected that it will be made explicit by the students how and why they used certain volume formulas to find their answer.
