CDW-G and Discovery Education are holding their fourth annual “Win a Wireless Lab Sweepstakes” to give schools the chance to win technology for their classrooms. Two wireless computer labs, each worth more than $40,000, will be awarded as grand prizes. Each grand prize includes 20 HP or Lenovo Tablet PCs, a PolyVision Lightening RM Easiteach calibration-free interactive whiteboard, an HP or InFocus LCD projector, and an HP LaserJet printer. The wireless labs are installed on a Bretford wireless cart with three Netgear access points, enabling educators to transport the labs easily from one classroom to another. Additional prizes include Toshiba projectors, Lexmark printers, Adobe software, Brother printers, and $500 worth of multimedia resources from Discovery Education. Public and private school teachers, administrators, and technology specialists can enter by filling out an online form. Winners will be chosen at random and will be announced in July.
