## Percent as a Means to Compare Fractions

Icon:

In this video segment from Cyberchase, the CyberSquad looks at data on the Squitters' jumping attempts. They first convert the fractional results to equivalent fractions with denominator values equal to 100. Then they notice that these fractions can be written as percents.

## Bianca the Spy

Icon:

In this video segment from Cyberchase, Bianca daydreams about being a spy. In order to save the video games of the world from being totally eliminated, Bianca must replace a crystal in the video game eliminator. To do that safely she must follow a specific number of steps and then perform the inverse of those steps.

## Predicting Travel Time Using Line Graphs

Icon:

In this Cyberchase video segment, Harry wants to visit his grandmother. He decides that the cheapest way for him to get there is to travel by unicycle, but he wonders if he can get there before dark. Using a line graph, he tries to predict the amount of time it will take to travel the twenty miles, assuming he travels at a constant speed. Once he sets out on his unicycle, he charts his progress on a new line graph. After the first hour he appears to be ahead of schedule, but he is not able to keep up the pace and soon finds himself falling behind.

## Balancing Equations with Multiple Terms | Cyberchase

Icon:

In this video segment from Cyberchase, Inez and Digit are attempting to gain access to a machine in order to save Sensible Flats from disaster. First, they must balance a scale to get the correct numeric access code. In order to do that they have to balance a scale using four weights on each side. They soon learn that adding or removing the same weight from each side does not upset the balance of the scale.

## Calculating Rectangular Area | Cyberchase

Icon:

In this video segment from Cyberchase, the CyberSquad must measure two differently-shaped parcels of land to determine which has a larger area. The CyberSquad uses tarps, fence posts, and finally a grid made out of rope to count squares and determine the area of each parcel.

## When Does 50/50 Become 50/50? | Cyberchase
