CDW-G and Discovery Education Wireless Technology Labs to Transform Tennessee and Maine Classrooms

Two "Win a Wireless Lab" Winners Receive $40,000 Wireless, Mobile Computer Labs to Improve Student and Teacher Access to Integrated Technology Resources

Vernon Hills, Ill., and Silver Spring, Md. - July 10, 2006 - CDW Government, Inc. (CDW-G), a wholly owned subsidiary of CDW Corporation [NASDAQ: CDWC] and leading source of Information Technology (IT) solutions to governments and educators, and Discovery Education, the leader in digital video and multimedia-based learning, today announced Central Middle School in Murfreesboro, Tenn., and Fischer Mitchell Elementary School in Bath, Maine, as the grand prize winners of the 2006 "Win a Wireless Lab" sweepstakes. CDW-G and Discovery Education sponsor the annual sweepstakes to encourage teachers to expand their use of technology in the classroom.

"Technology is a driving force in education today," said Chris Rother, group vice president, sales, CDW-G. "The entire learning community benefits from the new opportunities that technology, like tablet PCs and interactive whiteboards, brings to the classroom. Wireless technology, especially, frees teachers to move around the classroom, interact more with students and encourage their participation in lessons."

Bill King, a technology teacher at Central Middle School in Murfreesboro, Tenn., won a wireless lab with 20 Lenovo tablet computers, a PolyVision Lightning RM Easiteach calibration-free interactive white board, an InFocus LCD projector and an HP LaserJet printer. "We want as many students as possible to benefit from the lab," King said. "We will encourage teachers to use the lab as they introduce students to new curriculum topics and concepts." The Central Middle School building is 50 years old and part of a growing school district that struggles to keep older buildings on par technologically with the newer facilities. "The wireless lab will give our students the opportunity to use technology every day like their peers at other schools in the district," King noted.

Kitty O'Neil, a speech and language teacher at Fisher Mitchell Elementary School in Bath, Maine, won a wireless lab with 20 HP tablet computers, a PolyVision Lightning RM Easiteach calibration-free interactive white board, an HP LCD projector and an HP LaserJet printer. "The wireless lab will help us overcome some of the budget cuts the district has experienced, as well as prepare my elementary students for the laptops they will receive in middle school as part of the Maine Laptop Initiative," O'Neil said.

CDW-G and Discovery Education will provide installation and training, as well as oversee the launch at both schools in the fall. The wireless labs are installed on a Bretford wireless cart with three NETGEAR access points enabling educators to easily transport the tablet PCs, projector and printer from one classroom to another. In addition, an APC back-up power protection unit, 20 Corel software licenses and a networked collection of Discovery School life, earth and physical science CD-ROMs are included with both grand prize packages. Each grand prize is valued at more than $40,000. The 2006 "Win a Wireless Lab" sweepstakes awarded 40 educators from 22 states prizes totaling nearly $100,000.

"The number of educator sweepstakes entries grew 80 percent in 2006 with more than 146,000 entries," said Paul Thomas, Senior Vice President at Discovery Education. "The ‘Win a Wireless Lab' sweepstakes continues to provide schools with the opportunity to win technology that might otherwise be beyond their budgets. We are pleased to partner with CDW-G on a project that has become so successful."
