8th grade · Geometry
Know the formulas for the volumes of cones, cylinders, and spheres and use them to solve real-world and mathematical problems.
2 interactive, auto-graded activities for 8th grade students practising 8.G.C.9. Mini Labs put the standard to work in a real scenario; Skill Practice builds fluency on the standard alone. Every one is randomized per student, so each learner gets their own numbers.
Pack a mobile medical unit in this interactive real-world math challenge. Students calculate volumes of cylinders, cones, and spheres, then use sliders to choose equipment quantities that help at least 100 patients while staying within storage limits. A powerful application of CCSS 8.G.C.9 focused on decision making and optimization.
Design and launch a deep space probe in this interactive real-world math challenge. Students calculate and compare volumes of cylinders, cones, and spheres to meet fuel, sensor, and payload constraints. Using realistic engineering decisions and auto-graded inputs, learners apply 8.G.C.9 concepts while optimizing space and making mission-critical choices.
