Now available for younger readers, the Readingpen works just like a highlighter, scanning over difficult words or sentences to hear them read aloud. The pen also provides dictionary definitions, thesaurus entries, and syllabication. Offering a vocabulary of more than 240,000 words from the American Heritage® Children’s Dictionary and Thesaurus, the pen features an integrated speaker, LCD screen, headphone jack, and two AAA batteries. Teachers can block access to the dictionary and thesaurus, making it useful even in testing situations.http://www.etacuisenaire.com
