SNOW DAY TO BE EXACT 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. Math Topic: Estimation SECRETS OF SYMMETRIA In his passion for symmetry, Dr. Marbles has created Symmetria, a harmonious cyberplace where everything is made symmetrical by a symmetrizer. Hacker steals the machine and reprograms it so that he can undo symmetry. The kids must master the properties of symmetry before Hacker destroys beauty, balance and harmony throughout all of cyberspace! The Big Idea: Symmetries are patterns you can find hidden within many objects that create balance, order, and a pleasing regularity in the world around us. Math Topic: Symmetry AND CLOCK LIKE AN EGYPTIAN Dr. Marbles finds the encryptor chip, which he needs to delete Motherboard's virus, in an ancient pyramid.
