LOST MY MARBLES 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. Math Topic: Navigation ZEUS ON THE LOOSE 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 to use. Math Topic: Fractions Math Message: If you have an amount to share equally, the more equal shares, the smaller each share. AND THEY COUNTED HAPPILY EVER AFTER Hacker kidnaps the King of this fractured fairy tale 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: Let numbers stand for things in a regular pattern, and you have the power to keep track of anything and everything on Earth. Math Topic: Number Sense
