CAMBRIDGE, MA — November 1, 2005 — Houghton Mifflin Company and Six Red Marbles announced today that Houghton Mifflin's Discover! Simulations product has been selected as a finalist in the Education and Learning category for the 10th Annual MITX Awards. Produced by the Massachusetts Innovation & Technology Exchange, the MITX Awards recognize excellence in the creation of interactive technologies designed, produced or developed in New England. The Discover! Simulations are an integrated technology solution for the new Houghton Mifflin Science textbook program for grades K–6.

Begun in 1996, the MITX Awards is the largest and most prestigious awards competition in the country for technology innovations and celebrates the best creative and technological accomplishments emerging from New England.

"This is a special milestone for the organization and the commercial Internet industry as a whole, both of which have seen significant change, myriad successes and unprecedented growth over the past decade. As technology advances, we will be at the forefront of those advancements," said Kiki Mills, executive director of MITX. "Our awards finalists continue to raise the bar, and their work is a true testament to how interactive technology has become a core technology for businesses across all industries, nonprofits and educational institutions."

The Discover! Simulations for grades K–6 consist of 42 Flash-based science simulations that provide an interactive way for students to explore real-world science concepts. An integral part of Houghton Mifflin's new science textbook series, the Discover! Simulations offer students an interactive way to explore concepts presented in their textbooks while meeting both state and national science standards. With six simulations per grade level — 2 Earth Science, 2 Physical Science, and 2 Life Science — students are provided with a variety of learning experiences.

"Our Discover! Simulations help deliver key science concepts in different ways and bring science to life for young minds," said Kirby Mansfield, vice president and editor-in-chief, Mathematics, Science, and Instructional Technology, Houghton Mifflin School Division. "We are pleased that our collaboration with Six Red Marbles has been recognized by MITX, in the nation's premier technology award competition."
