Fortress of Attitude
Hacker decides that he can force cybersites to surrender by annoying them big time. He broadcasts his loud and obnoxious voice across the vastness of cyberspace from a massive statue shaped like the arrogant Hacker himself. The kids and Digit are sent by Motherboard to the Northern Frontier, where they carry out a Mission Impossible style scheme to silence the statue and disable Hacker's intimidation. Using their skills at measuring length, the kids make their way up through the inside of the booby-trapped statue to Hacker's pointy chin and big mouth. But can they shut him up before Hacker shuts them down? The Big Idea: To measure length and communicate your results easily and precisely, identify a system of units based on a single standard length that everyone using it agrees on. Math Topic: Linear Measurement NCTM Links: Measurement.

And They Counted Happily Ever After
(topic: Number Sense) - Hacker kidnaps the King of this fractured fairytale world, and demands a ransom of golden eggs. The Wicked Witch then casts a spell, taking away everyone's ability to count and making it impossible for the fairy tale folk to gather the required large number of eggs. With the safety of the King at stake, the kids must help the fairy tale folk understand the role of place value in our number system before time runs out! The Big Idea: With numbers and a system, you have the power to keep track of anything and everything on earth.

A Battle of Equals
Hacker pollutes cyberspace with dangerous cyberstatic by tampering with four satellites designed to keep everything free from cyber- static cling. But is his plan only to trash cyberspace - or does he have something even more devious up his cloak? The kids learn the answer as they use balance scales and equations to restore the satellites and save Motherboard. The Big Idea: You can use an equation - a statement that two different expressions are equal to each other - to find unknown values that make the equation true. Math Topic: Balancing Equations NCTM Links: Algebra, Representation, Connections.

A Time to Cook
Hacker finds the part he needs to fix his Magnetic Magnotube - a machine that would disable Motherboard forever - in a most unlikely place. All he has to do to get it is win a cooking contest on the hit cyberspace TV show, The Fearless Chef. Hacker's plan? To kidnap his competition. But the Cybersquad is on to him. The girls go on a rescue mission to save the Fearless Chef, while Matt and Digit take on Hacker. Digit is already a celebrity chef, so this should be a piece of cake. They must race the clock and Hacker to cook three delicious dishes in three outrageous locations. Will Digit beat Hacker? Only time will tell. Math Topic: Elapsed Time; NCTM Links: Measurement.

A Day at the Spa
(topic: Combinations) - Hacker finds the Krystal of Kalmoor, the powerful orb that will give him eternal power. By possessing the Krystal, Hacker can roam cyberspace and create havoc without having to recharge his power. When the kids and Digit arrive to retrieve the Krystal, they are stymied by a series of switches, levers and buttons. Faced with the challenge of too many choices, the kids discover the value of lists, tables and, yes, tree diagrams! The Big Idea: Overwhelmed with choices? Lists, tables and tree diagrams help you master the combinations.

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. Math Topic: Negative Numbers NCTM Links: Number & Operations.

On The Line
When Digit heads off alone to dispose of the powerful Network Interface Card (NIC), calamity strikes. A sinister cyvulture steals the NIC right out from under Digit's beak and gives it to Hacker! At a secret location on the Northern Frontier, Hacker uses the NIC to power up his dastardly Transformatron and transforms himself so he can slip into Control Central and replace Motherboard. To find the Transformatron and reverse its power, the CyberSquad must discover how an object can be pinpointed using two straight lines - before Hacker takes over Cyberspace forever!

The Icky Factor
Hacker launches his most dastardly and secretive scheme ever! He's building a device so dastardly, victory over Cyberspace is in his sights. His cunning contraption calls for an unusual power source - the Electric Eel of Aquari-Yum. To get the eel, Hacker traps its guardian, cyberslug Icky, far from home. The kids and Digit must use the concept of factoring to save the day. But can they rescue Icky and stop Hacker from stealing the Electric Eel?

Penguin Tears
Hacker's secret quest continues, with the nefarious `borg on the hunt for the next piece of his mysterious machine. His search for the legendary Prism of Penguia takes him to snowy Cyberia.

Blowin' in the Wind
Hacker pursues a career as a singing idol and goes on tour, leaving behind a book that contains the secret to curing Motherboard's virus, buried in the windiest place on the Northern Frontier. Slider and the CyberSquad are determined to find it...but to do so they must discover how to measure wind speeds in different places so they can compare them. Can the kids find the book before Buzz and Delete, who want to steal Hacker's secret? Stay tuned for the surprise ending!

Snow Day to Be Exact
(topic: Estimation) - Hacker steals the powerful sunisphere from Solaria, causing the cyberworld's sunny vacation paradise to be covered in snow! In a fun-filled chase across the snowy terrain, the kids discover the power and speed of estimation in order to recover the glowing orb from Buzz and Delete before the temperature reaches zero and the site freezes over forever. The Big Idea: Sometimes using a close answer is good enough for the problem you are solving. ~

Hugs and Witches
It's Valentine's Day, and Hacker captures Doctor Marbles and Lady Ada Lovelace (Jane Curtin), placing them inside a time machine invented by the mathematically-minded Lovelace. The kids and Digit must decipher a series of poems left behind by Lady L, and free them from the time machine before it time travels to the nether world of cyberspace - never to return! Will the kids get there in time, or will Valentine's Day bring nothing but broken hearts?

When Penguins Fly
Penguins can't fly - or can they? In Cyberspace, on one special night each year, the penguins of Penguia take flight to deliver gifts to young borgs across the virtual universe. For the first time ever, the CyberSquad's friend Fluff is participating, and invites his pals Matt, Jackie, Inez and Digit to join him in the impressive Penguin March. They head to the Ice Palace, where the gifts are made and where magic snowflakes are sprinkled on the penguins so they can fly. But Hacker, up to his usual ruinous tricks, doesn't want a happy holiday (let alone happy little borgs) so he creates a giant ditch in front of the Ice Palace and traps all the penguins in its icy depths! The CyberSquad must get the penguins ice-shoes so they can climb out before midnight, but how many do they need? With too many to count, the answer lies in the kids' ability to sample the penguin population to make a close estimate. Can the CyberSquad save the penguins and their favorite holiday too??

Totally Rad
The dastardly Hacker (Christopher Lloyd) takes over the Radopolis cybersite, declaring himself King in "Totally Rad," the season premiere of CYBERCHASE. In an effort to dethrone him, the kids challenge the Hacker's extreme team to a winner-take-all skate-off. There's just one catch: high-scoring tricks need as much area as possible and the field keeps mysteriously changing! With Digit ( Gilbert Gottfried) as coach, the kids put on a dazzling display of blading, boarding, and biking, but can they match their performance to the changing arena? The Big Idea: Different shapes bounded by the same perimeter can enclose very different areas. Math Topic: Perimeter/Area.

Team Spirit
Interest is lagging in the annual Mount Olympus Games, attendance is sagging, and Zeus is not happy. How can he restore the spirit of competition? With lightning bolt speed, he pits Team Motherboard, coached by Digit, against Team Hacker, coached by Wicked, The teams have to compete in the Triadditon, a relay-type race made up of an obstacle course, a swim race, and a foot race where each competitor does one event and tags their teammate to do the next. Bragging rights and hero worship go to the winners. But Wicked and Digit have their hands full when Hacker and Matt both insist on running the final event so that they can claim Zeus's glory. How can the kids convince Matt to let go of his personal pride - and rivalry with Slider who subs for the injured Jackie-for the good of the team?

A Fraction of a Chance
When Matt, Jackie and Inez get stuck in the vortex of a cyberportal, it's up to Digit to rescue them. He just needs to find the U.V.O. - the Universal Vortex Opener. But all the portals are jammed, so how's he supposed to travel anywhere? Assistance comes from a surprising source - Wicked! Digit and Wicked must work together to solve the puzzling clues that will reveal the location of the U.V.O. But they have to hurry - if the kids aren't rescued soon, they'll dematerialize! Can Digit and Wicked find the UVO in time? And is there even a fraction of truth to Wicked's claim she only wants to help out? EDUCATIONAL OBJECTIVE: When you share parts of a whole, it takes two numbers to tell the story - the top and bottom numbers of a fraction.

Zeus on the Loose
(topic: Fractions) - When the kids fail to stop Hacker from stealing Pandora's box in mythological Greece, they must solve a riddle and complete challenges to satisfy Zeus and earn a second chance. In the course of their adventure, Matt, Jackie and Inez discover that a fraction is a problem in sharing. The challenge is solving increasingly difficult problems in sharing while they confront a myriad of mythological creatures. The Big Idea: When you need to divide things up into parts and share them, fractions are the numbers you use.

Father's Day
It's the annual Father's Day Parade in Tikiville, and Creech's father, Max (Matthew Broderick), is this year's Cyberdad of the Year. Max was once a schoolmate of Hacker's - and continually bested Hacker in all of their endeavors. Hacker has decided it's time to get even and this time he's got a really clever plan... Using secret codes and a band of bad guys, he rolls into action, cleverly changing the code each step of the way to keep those "earthbrats" from catching on. Will Hacker succeed in spoiling Father's Day and embarrassing Max? Or will our heroes figure out the pattern to his codes in time to stop him?

The Case of the Missing Memory
Under the guise of a peace mission, Wicked arrives at Control Central with a handful of bad guys. But someone's up to no good, and steals Motherboard's precious Memory Integrator. Whodunit? Where is it?? And what does it look like??? Digit and the kids must figure out what they know - what they don't know - and what they need to know. Can they do it all before Motherboard's memory is lost forever?

The Emperor Has Snow Clothes
Hacker has crowned himself Emperor of Penguia and deposited the real emperor as a frozen statue in a distant corner of the site. The CyberSquad arrives just as a crippling snowstorm makes its way across Penguia in a path that seems destined to collide with their rescue. Digit uses updates on the storm's progress from cyberweathercaster Stormy Gale (Janice Huff) to help the kids track the storm. Will the kids be able to predict where and when it will hit next - or will the storm stop them from saving the Emperor from a frozen fate?

Eureeka!
(topic: 2- & 3-D Geometry) - Pursued by Hacker, Digit lands on cybersite Eureeka, where his mission is to find Professor Archimedes - 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 two-dimensional rods where his chip factory should be. The kids arrive to help, and discover that by linking the two-dimensional rods together into certain geometrical patterns they actually create a surprising three-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 (two- dimensional), and join them together, you can discover new shapes that, instead of staying flat, rise up to make three-dimensional objects.

Chaos As Usual
Introducing Memoryville, home to a vast storehouse of Cyberspace data, where The Slugball Open, a Cyberspace version of baseball, is in progress. In their attempt to win for a day the Key to the City, Team Motherboard has made it to the finals ... along with, you guessed it, Hacker! Unbeknownst to most (except, of course, to Hacker), this Key opens all doors to the city-including the door to the data storehouse! With surefire plans to win, Hacker can hardly wait to delete the data and create untold chaos. Undaunted by the awesome array of Hacker's bad guys, Team Motherboard discovers distinctive patterns to these nefarious sluggers' past performances. But can the hit charts they develop be enough to help the good guys win?

Lost My Marbles
(topic: Navigation) - A day at the library turns into a cyberventure when Jackie, Matt, and Inez learn that Hacker has kidnapped Dr. Marbles, the only person who can save Motherboard from an evil virus! The team learns to use a map as a mathematical tool as they navigate across a cyber island in search of Marbles...then try to escape before a huge earthquake turns the island inside out! The Big Idea: A map is a mathematical tool you can use to find your way from one place to another, anywhere on earth.

The Flying Parallinis
When Hacker strands Jackie atop Mount Wayupthere, the rest of the CyberSquad has to act fast to save her. In their search for the elusive Diamond Joe - the mysterious figure who holds the secret to Jackie's release - the CyberSquad meets spunky TW, a young Parallini who agrees to help them. Can they discover the power of parallelograms in time to launch a daring rescue mission?

Find Those Gleamers!
(topic: Algebraic Variables) - The Hacker challenges Jackie, Matt and Inez to a contest on cyber-wide television! In order to prove to all of Cyberspace that Hacker's not as powerful or smart as he seems - the kids return to Topsy-Turvy Island on the Northern Frontier for the contest. Their mission is to power up a Mini-Wreaker using cyber-fireflies of varying power before the island turns inside out at sunset. The kids must use algebraic equations to determine how many Gleamers - and how much power - they'll need. The Big Idea: When you use a letter to stand in for a number that repeats or changes in a problem, you can simplify the arithmetic and make the problem easier to solve.

A World Without Zero
Why does glamorous Gollywood go ga-ga when a nobody like Mister Z skips town? It's a fiendish Hacker scheme, of course. Because of a poison pen campaign devised by Hacker, Mister Z feels worthless and unwanted. He decides to leave Gollywood, taking his zeroes with him. The sudden disappearance of the number zero causes confusion and chaos, exactly as Hacker planned. As Hacker becomes the biggest star in Gollywood, the kids and Digit must show Mister Z he does indeed have a value by demonstrating the importance of the number zero.

Harriet Hippo and the Mean Green
Hacker infects Motherboard with a new virus -- one that causes her to make cyber-citizens act mean. Digit and the kids go in search of an antidote: 2/5 of the Electro-Root, 2/8 of the Healing Stone, and 1/3 of a box of Hacker's wig gel -- a strange antidote indeed! Will the young cyber-heroes be able to gather the ingredients and figure out how to properly mix these odd fractions before it is too late? The Big Idea: Fractions that look different can represent the same portion of a whole. Math Topic: Equivalent Fractions.
