Mother's Day (Episode #206)

PBS Kids: Sun, Sep 30, 2012 -- 9:30 PM

Special Holiday Episode!" It's Mother's Day in cyberspace - and Hacker is determined to ruin it for everyone, especially Motherboard, by derailing the train that picks up the rare and colorful Madre Bonitas. This beautiful flower symbolizes Mother's Day, and it must be harvested on this one day only. It's a race against time, as the kids and Digit try to repair the breaks in the line and save Mother's Day. The Big Idea: Use a decimal point to join tenths with whole numbers and you have a decimal system you can use to easily record, compare and combine whole numbers with fractions. Math Topic: Decimals; NCTM Links: Number and Operations.

Send in the Clones (Episode #119)

PBS Kids: Sat, Sep 29, 2012 -- 9:30 PM

(topic: Multiplication) - Hacker's plan to clone himself so he can wreak havoc throughout cyberspace in many places at once, goes haywire when his newly invented Clonitron clones Delete instead of himself. But Hacker takes advantage of the mishap by sending the Delete clones to takeover the R-Fair City cybersite. To complicate matters, every time Delete sneezes - his clones multiply even more. As the problem escalates, the kids do the math to keep track of the number of clones as they increase. Meanwhile, Cy Clone, a famous clone catcher sent to the site by Motherboard, vacuums up the clones - while Digit tries to get the Clonitron away from Hacker. The Big Idea: Multiplication is just repeated addition. If you're having trouble multiplying, you can always add to find your answer.

Problem Solving In Shangri-La (Episode #118)

PBS Kids: Sat, Sep 29, 2012 -- 5:30 PM

(Topic: Problem Solving) - Hacker is holding the kids captive aboard the Grim Wreaker, when a storm forces the Wreaker to land on a snowy mountaintop. They are taken prisoner by a peaceful but mysterious Zen Master, who devises a game of strategy to test their problem solving skills. The winner of the game will be set free - the loser will remain a prisoner. In the battle of brainpower, the kids discover that each of them has a different way of solving problems - and that despite anger and frustration, they need to be tolerant of these differences. Hacker, of course, has his own way of solving problems. Working together, the kids find a way to defeat Hacker and gain their freedom. The Big Idea: Treat tough math problems like a challenging game. Set a game plan, and as you play, see how it goes. Take time to review and revise before playing again. Work on your problem as long as you can, but stop before anger and frustration overtake your desire to play.

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.

But Hacker unfolds a brilliant scheme to crack open the Skywall - using the Wicked Witch's Voice! Can the kids use models to outwit Hacker before Wicked sings?!! The Big Idea: Make a model - a simplified version of something complicated - and you can easily and safely understand how it works. Math Topic: Using Models NCTM Links: Geometry.

In a race to rebuild their cybercraft and save Marbles, Digit and the kids learn to trade and barter and eventually create a monetary system. But who will finish first?!! The Big Idea: Instead of trading what you have for what you want, you can make it easy to buy and sell by creating a system where you exchange goods for tokens of different fixed values - money!

Cool It (Episode #114)

PBS Kids: Sun, Sep 23, 2012 -- 9:30 PM

(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.

Hacker's luck changes, and good things begin happening to him. When Motherboard realizes what Hacker has done - she sends the kids and Digit to Hacker's hideout in the Northern Frontier to help the Lucky Charms escape. The kids use logic, Venn Diagrams and the understanding of the words "and", "or" and "not" to free the Charms. The Big Idea: When you have to choose from a confusing mix of possibilities, you can use logic - a set of tools for thinking clearly - to sort out your choices so you can get exactly what you want.

But the Mummy who guards the pyramid finds Marbles. When the kids and Digit arrive, they must work their way through the chambers of the pyramid - find Dr. Marbles - and escape before a trap set by the Mummy seals them inside forever. How much time do they have? Unfortunately, they have no clock or watch to tell them how much time has gone by. Is the mission impossible? Not for our kids! The Big Idea: To measure the passage of time, choose a starting point and count up the beats of something that repeats at steady, regular intervals.

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.

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.
