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?

Digit disappears while visiting his friends the Scritters, so Motherboard sends Matt, Jackie and Inez to investigate. They discover that Hacker has found a supply of Magnetite, and will use it to fill up a rocket capable of erasing all of Motherboard's memory disks. Can the kids stop Hacker before he collects a hundred percent of the Magnetite he needs to launch the rocket, or will Motherboard be shut down once and for all?

The CyberSquad and their new friend Scanner embark on a quest to build a new Encryptor Chip for Motherboard and cure her virus. With Hacker in hot pursuit, the kids must run, ski, canoe and climb their way to the end of the mission. In the process, they learn that a little activity over time adds up. But will they also cure Motherboard? Big idea: To have fun and be healthy, get up and moving for sixty minutes each day. Math concepts: Data Representation/Tables.

When Wicked puts a CyberSquad Seal of Approval on her new "Wickedy Brooms," it's up to Matt, Jackie, Inez and Digit to make sure the brooms are as good as Wicked claims. They try them out, figuring out their speed - how far the different brooms go in a given amount of time. The brooms pass the test - but Wicked doesn't. They must race to Control Central and save Motherboard before Wicked's scheme succeeds! And where's Hacker? And what will he do when he finds out Wicked is trying to take over his turf? EDUCATIONAL OBJECTIVE: You can use speed - the distance you travel in a unit of time - to tell how far you will go in any amount of time.

Sensible Flats has been "Hackerized" - all the town folk look and act like the dastardly villain. But get this: Hacker didn't do it! While he sets out to find out who could have pulled off this fantastic feat, the CyberSquad rushes in to save the town. To do so, these novice climbers must scale a rocky cliff in less than 3 minutes. Can they improve their rock-climbing skills in time or will they be Hackerized themselves?

(topic: Liquid Volume) - Determined to destroy Motherboard in any way possible, Hacker cleverly clogs up her cooling system. Digit brings the kids into cyberspace to help fix her, but the special coolant Motherboard needs, cryoxide, is found only in Castleblanca - and the 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.

While enjoying a little R & R in Solaria, Hacker is delighted to see Wicked, who is also on vacation-but she's not alone! She's partnered with Nug Grommet, the handsome cyber-surfing champion in a dance contest. Turning even greener with jealousy, Hacker enters the contest to prove his superiority. Only there's one small problem-who can he coerce into being his partner? Enter the CyberSquad. Observing Jackie's prowess on the dance floor, Hacker has Buzz and Delete detain Inez, then forces Jackie to teach him the moves and dance with him in exchange for Inez's safe return. As the contest unfolds, it becomes apparent that the judges lack a workable scoring system to decide the winner. Determined to help Inez, Matt joins the judges to find a way to score the contest. And, as Wicked points out, it had better be fair or she will wreak her revenge! Should Matt give Hacker and Jackie a higher score than Wicked and Nug so Inez can go free? Or judge the contest fairly and hope Digit rescues Nezzie in time?

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!

Hacker has finally captured those Earth brats on the Wreaker! Before he can decide what to do next, an alarm goes off...the Wreaker is out of fuel! He lands on the nearest cybersite, Ekardia, an eerie place with no one in sight and no way to contact anyone. He has only one choice: enlist the CyberSquad's help so they can ALL get back home. They find one Ekardian left behind - Ted. Everyone else left because Ekardia ran out of frixite, the nonrenewable resource they used to power everything. Now Ted lives off the natural resources around him. If Hacker and the kids are going to get home, they and their resourceful new friend will need to learn from Ekardia's past. Can they also help save its future?

(topic: Patterns) - The diabolical Hacker wreaks havoc when he steals the power pods of Poddleville, a cybercity filled with patterns. Our heroes must use math and logic to crack the double pattern that unlocks the Poddles' cyberpower vault before Hacker and his henchmen do! The Big Idea: Patterns are sequences that repeat or change in an orderly way. You can use patterns to predict the next step in solving a problem.

Hacker has discovered an army of awesome creatures he can use to rule cyberspace, but they are carved in stone on the walls of the Pyramid of Jimaya. To bring the animals to life, he must steal the Sphere of Being, a magical orb closely guarded by three ghosts (Hacker's worst nightmare). How can he distract them so he can steal the Sphere? Opportunity knocks when he tricks Jules, recently hired as tour guide, into pushing the wrong button and falling, along with the kids and Creech, into an underground arena from which there is no escape! Confronted by the Jam Master, the guardian of the pyramid, and the Pyramid's three ghosts, the kids are told they can go free if they can overcome the ghosts in a game of Jimaya Jam. The game is like basketball except for a few small quirks: When Matt tries to dribble and move the ball across the court, it breaks! And he can't move from where he stands on the court once he receives it. Coach Jackie struggles with a game plan until the kids realize that diagramming her plays makes it a whole lot easier to follow them. Down to their last ball, stopping Hacker rests on their ability to diagram and execute the right play.

Perfectamundo isn't so perfect anymore - the trash is out of control! A giant garbage heap threatens to break through the cybersite's dome, and the CyberSquad must become garbologists in order to reduce the rubbish. Hacker, meanwhile, is digging through the very same heap for some mistakenly discarded seeds that will allow him to grow an army of monster plants to take over Cyberspace. Will he find the seeds before the Perfectamundians solve their trash problem? Or is the dome doomed?

(topic: Probability and Chance) - Disguised as a gypsy, Hacker lures Digit to a fantastic cyber amusement park and holds him captive. When the kids arrive, they analyze the games of chance, figuring out which games are fair and which ones are not, and use what they learn to find Hacker and beat him at his own game before it's too late! The Big Idea: A game of chance is fair when nobody can tell who will win, but everyone has the same chance of being a winner.

Kids in glamorous Gollywood have no safe place to play. When they discover an empty lot that can be converted to a park, they have only one opponent: Hacker. He wants the lot for his new Gollywood Tower, which he claims will broadcast entertainment to all of Cyberspace. (The tower is really meant to corrupt Motherboard's hard drive.) The CyberSquad goes up against Hacker at a city council hearing. Will they get their park, or will Hacker dazzle the council into approving his tower? Big idea: Communities need to provide safe, inviting outdoor spaces where kids can play and be physically active. Math concepts: Data Collection and Representation: Surveys, Tally Marks.

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.

To prove once and for all that he's smarter than the CyberSquad, Hacker challenges the kids and their friends to solve a series of puzzles.

Digit and the kids must help Shari Spotter (of Frogsnorts School for Sorcerers) make the magical Cosmic Crumpets before Hacker crashes the Sorcerer's Ball and becomes the most powerful magician in Cyberspace!

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?

Bird lovers across Cyberspace have arrived at the Migration Celebration - a magical event where the rare teal-footed trillers flock once every five years. But when the trillers are a no-show, Professor Bobson, host of the event, knows something is amiss. After cancelling the celebration, phone calls and social media posts start reporting triller sightings all over Cyberspace! The Professor and kids recruit dozens of citizen scientists to record their observations when they see a triller. But in the chaos, they forget Digit, the biggest triller lover of all, can be a big help! When all the citizen scientists have reported back, it leads to a shocking discovery. What is the data telling them? And can Digit help crack the case?

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?

Someone has stolen the legendary cyberbeast Choocroca from cybersite EcoHaven, and the only clue is the culprit's footprint. Using the principles of "body math," the CyberSquad has to sleuth out who took Choocroca, and rescue the massive beast. The suspects are members of a safari team -- one of them is secretly working for Hacker, who wants to capture the creature and use it to takeover Cyberspace. The CyberSquad must use forensic science to build their case and find both the culprit and the critter before Hacker gets his way.

Digit's friend Pearl says her town is in trouble. The water levels in Canalia, a beautiful cybersite connected by canals, keep getting lower, but Canalians don't see the problem. So Pearl built a time machine to prove she's right! She travels with the CyberSquad into the past to see how much higher the water levels were, and the kids promise to help convince Canalians to change their water-wasting ways. But when they invite everyone to travel through time and see what happens, the time machine goes missing! Hacker has stolen it! Can the kids get the time machine back before Hacker resets the course of cyberhistory?! And can Canalians be convinced to protect their future by changing the present?

(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.

The citizens of Factoria have been put back to work at a toy factory where they get free meals. The problem? The benefactor is none other than Hacker, and the meals all come from vending machines. The CyberSquad and their new friend--a little Factorian girl named Zoreen--suspect Hacker is up to no good, and they discover he's not making toys, but spy planes! To get the Factorians out of Hacker's clutches, the CyberSquad must show them how to grow their own food. Can they put Hacker out of business for good? Big idea: Delicious, healthful vegetables don't just come from the store. They grow from seeds - and you can grow (and eat) them yourself! Math concept: Area.

It's the CyberSquad's most ingenious plan ever - and most dangerous! If they can insert a new memory chip into Hacker's H-Drive, they can turn him from evil to good. Once he's been shrunk and is inside Hacker, Matt's mission goes like clockwork until a force field is activated and envelops the H-Drive. All seems lost until Digit remembers a robot that Dr Marbles made that can break through any force field. They can shrink it down and send it in to help Matt... but must first figure out how to make it follow their commands. Can Inez, Jackie and Digit program the robot in time?

Digit is going on his annual visit to Mermaidos, an underwater cybersite filled with merfolk, to visit one of his best friends in the whole cyber-world-Eugene. The two of them are great buddies who love to play underwater games, frolic with fish, and do other wacky water things in this idyllic underwater paradise. When Digit arrives, something is wrong. Mermaidos is murky and warm and the fish are leaving in droves. Digit feels terrible for his pal Eugene and promises to do what he can to make things right. It turns out Hacker has put a plan in motion to turn Mermaidos into his own personal hot tub! He is making the water hotter and hotter, raising the temperature to a hot 100 cyber-degrees- a temperature that would make Mermaidos uninhabitable for the Mermaidians and force them to move out. It is up to Digit and the CyberSquad to stop Hacker's plan, reverse the thermal pollution and help save Eugene's home.

Digit is pet-sitting in Golftopia, taking care of Dewey, a lovable Deedle Beast. But suddenly Dewey starts going berserk on his daily walks. What's going on?!

The CyberSquad investigates to see what's causing all these changes. Is Hacker back to his old tricks? Or has he finally had a change of heart? And what's with the sparkly purple dots on the sculptures? EDUCATIONAL OBJECTIVE: Use a line graph to picture change and your eyes can quickly tell you when and how things are changing.

A televised skate-off will decide ultimate naming rights for the new Radopolis skate park. Will it be named after Slider, the ace skateboarder of Cyberspace, or The Hacker, the vainest villain in the virtual universe? When the power mysteriously goes out at the skate park, the CyberSquad and Digit must find a way to turn it back on before the nighttime skateboarding extravaganza. They decide to use solar panels to collect energy during the day that can power the park at night. But will they have enough area to install the panels, and enough time to collect energy before sundown? And if they do, can their friend out-skate the ace cheater of Cyberpsace?

When Hacker discovers that the liquid ooze that feeds the animals of EcoHaven also gives him a super energy boost, he decides to drain the pond and take the ooze home. He builds a fort around the pond, so the CyberSquad must figure out a way to get in without being noticed. They take inspiration from the Greek myth of the Trojan Horse and build a giant "Trojan Ducky." After testing a model of their invention to be sure it works, they hide inside the duck, and fool Delete into taking them to Hacker. But how will they stop Hacker's nefarious plot? EDUCATIONAL OBJECTIVE: Build a working model of your invention to communicate and test your ideas, and make necessary improvements so the invention works the way you want it to.

Matt is setting up the farm for his family's annual Halloween Pumpkin Patch Party and he is so excited! All his relatives come for the celebration, and even Grammy will be there this year! Inez and Jackie urge Matt to take a quick break and go into Cyberspace for Haunt-O-Rama at R-Fair City - an amusement park cybersite lit up to the nines for the Halloween holiday. The girls assure Matt he will be back home in plenty of time, and he agrees to go. But all their plans change when Hacker traps the kids on R-Fair City, hacking the portal system so they can't get back to Earth! (He thought he was keeping them out of Cyberspace for good, but alas, Buzz and Delete botched their task yet again.) Upset that he came to R-Fair City in the first place, Matt is worried about missing his family's party. The kids must find enough energy on R-Fair City to power Digit's old Portal Rebooter and fix the system. With the Halloween celebration in full swing, can they find enough big and small ways to save energy amid the bright lights? And will Matt make it back in time to see Grammy?

Hacker shows up at Motherboard Control Central. He pleads guilty to being the King of Chaos, but says he's sorry. He doesn't want to be a bad guy anymore.

And what will happen to the kids when they go inside Motherboard to track it down?

(topic: Finding Meaning from Data) - Dr. Marbles is captured by Hacker and taken to Castleblanca, a cyberspace version of Transylvania. Hacker's goal: transfer Marbles' brainpower into his newly-built robot named Megabyte! Summoned by Motherboard, the kids and Digit arrive with the knowledge that Hacker has taken Marbles to a castle - but which one? There are hundreds and hundreds of castles. To find Marbles, the kids must master the art of properly collecting data, organizing it and graphing the results - which are sometimes surprising! The Big Idea: Data is a lot more than a collection of numbers. When you gather it, organize and analyze it, you can discover useful information hidden in the numbers.
