Fill it Up!

(Not your red solo cup.)

Measuring volume of cones and cylinders.

In this activity you will be able to measure volume of cones and cylinders, compare similar shapes, and know the formulas for the volumes of cones and cylinders and use them to solve real-world and mathematical problems. (8.G.9) Math practices used: 1, 2, 4 and 6.


Using bathroom cups (cylindrical shape) and water cooler cups (cone shape), fill each cup with M & M's. How many M & M's will each hold? Now use beans, rice or another size of candy. How many did you count this time? Display data in a table. Compare data of cylindrical cup to cone cup. What do you notice? What is your conjecture? Does this occur every time? Why do you think this relationship exists? This activity could be done as centers with different objects at each station. Attached link has extension activities. Link
