An innovative, interactive series, Cyberchase challenges and delights viewers with its eye-popping mathematical adventures. Featuring the voices of Christopher Lloyd and Gilbert Gottfried, this action-packed animated show follows Jackie, Matt and Inez as they travel to the virtual vistas of cyberspace to foil the evil Hacker's attempts to take over cyberspace. Cyberchase teaches pre-teen viewers that maths is interesting, maths is fun, and maths is handy when you need to save the day. EPISODES LESS THAN ZERO The Leaders of Cyberspace have gathered to discuss Hacker's increasing influence, when they are suddenly interrupted by Hacker. Buzz and Delete, Hacker's henchmen, hide the leaders including Dr. Marbles, in the building and its' up to the kids to rescue them. Before long, the kids discover that they can only move between the building's levels by scaling its outside walls! So the kids turn the building into a giant ruler in order to keep track of the floors. And when they discover that there are levels beneath what they thought was "zero," the kids must tap into the power of negative numbers. The Big Idea: Numbers don't have to stop at zero! Negative numbers -- numbers that are less than zero -- can extend the range of what you can measure on a scale and give you the ability to compare numbers using direction as well as amount. COOL IT! Determined to destroy Motherboard in any way possible, Hacker cleverly clogs up her cooling system. Digit brings the kids into cyberspace to help to help fix her, but the special coolant Motherboard needs, cryoxide, is found only in Castleblanca - and supply is closely monitored! To bring back exactly enough cryoxide for Motherboard, the kids have to figure out the exact volume of Motherboard's tank. In the process, they discover the importance of a standard unit of measure - and fill a most unusual container with the precious cryoxide. The Big Idea: Just because one container appears bigger to the eye doesn't mean it holds more liquid than another. A container's volume depends on all its dimensions. EUREEKA! Pursued by Hacker, Digit lands on cybersite Eureka, where his mission is to find Professor Achimedes - the maker of the encryptor chip, a unique computer chip that can fix Motherboard. But Archimedes is nowhere to be found - only a pile of 2-dimensional rods where his chip factory should be. The kids arrive to help, and discover that by linking the 2-dimensional rods together into certain geometrical patterns they actually create a surprising 3-dimensional shape that leads directly to unraveling the mystery of Archimedes' strange disappearance. The Big Idea: When you follow simple rules to make flat geometrical shapes (2-D), and join them together, you can discover new shapes that, instead of staying flat, rise up to make 3-D objects.
