Understanding Concepts of Volume and Measurement: Bianca’s Babysitting Blues
In this video from Cyberchase, Bianca is babysitting infant twins. As she tries to give each twin the same amount of liquid baby formula, she discovers that all the baby bottles are different shapes. Learn how she finds two that hold the same amount. In the accompanying classroom activity, students estimate which of four empty containers has the greatest capacity and then determine which one does by measuring actual volume.

Standard Measures and Conversions within a System: Solve the Measurement Problem!
In this Cyberchase media gallery, the Cybersquad must try to follow a recipe exactly to create a mixture that will help cure their friend Slider. At first, the squad must find a way to ensure standard measures of the ingredients. When this proves only partially effective, they must determine how to make the mixture five times stronger. In the accompanying classroom activity, students use measurement tools, mathematical knowledge, and cooperation skills to create a complete class conversion chart on the board from a 1/4 teaspoon to 1 cup. They then use equations to prove that their conversions are accurate. This resource is part of the Math at the Core: Middle School Collection.
Grades: 45 
Standard Measures and Conversions: Liquid Volume, Milliliters and Liters
In this Cyberchase Media Gallery, explore key concepts about liquid volume, including standard units of liquid measure and how to convert between them. In the accompanying classroom activity, students create a complete conversion chart from the smallest measure (a fluid ounce) to our largest measure (a gallon). They use equations to prove that their conversions are accurate and learn to recognize mathematical relationships or patterns between the different measurements. This resource is part of the Math at the Core: Middle School Collection.
Grades: 56 
Hoop Dream: Use a Diagram to Solve RealWorld Math Problems
In this Cyberchase media gallery, a series of short videos shows how the Cybersquad diagram their own attempts to score a basket in a game called Jimaya Jam in order to win their release from confinement. In the accompanying classroom activity, student pairs play a game of their own called Player Plotting, in which students independently plot points on a coordinate plane and see if the diagrams they create from their points match.
