VERGENNES In 1609, Samuel de Champlain was the first European to travel the waters of the lake that would bear his name, a lake that was already an important maritime highway for Abenaki and Mohawk people. Teachers are invited to prepare for next years commemoration of the 400th anniversary of Champlains journey with a professional development workshop called Teaching Native History: A Trans-Cultural Approach. On Tuesday, Oct. 7, from 8 a.m. to 3 p.m. at the Bixby Memorial Free Library in Vergennes, teachers will have an opportunity to learn about the many native cultures of the Lake Champlain region. Registration and information are available by contacting Sigrid Lumbra at 802-828-0200. The fee for the workshop is $50, and recertification credit is available. To provide for a hands-on experience, attendance will be limited to 20.
