Big Ideas: Volume is a measure of space in real world situations. Some attributes of objects are measurable and can be quantified using unit amounts. Volumes of cylinders, cones, and spheres have comparable pieces such as radius and height. In this task, students will recognize a real world context for the volume of a cylinder that will help them understand how the formula is derived. It builds upon prior knowledge of the area of a circle as well as knowing that volume is a measure of space. It allows students to explore why the formula is what it is as opposed to just memorizing the symbols and not knowing what pieces to substitute into the formula. Vocabulary: cylinder, height, radius, area of a circle, volume of a cylinder, face Special Materials: Metric Rulers Coins (one penny, nickel, dime and quarter for each student, pair or small group)
