The main Cybrary is under attack. Hacker, disguised as an exterminator called the Vermin Vexer, has released a mysterious cyberbug that is systematically destroying certain information - but Ms. Fileshare, the overworked Cybrarian, is too busy to notice. When Hacker uses bar graphs to confuse Ms. Fileshare, the kids create bar graphs of their own to counter his contentions. Which graph will Ms. Fileshare believe? And what information is Hacker trying to destroy? Math Topic: Bar Graphs; NCTM Links: Representation. *With special guest star Jasmine Guy*
