MassCAN (the Massachusetts Computing Attainment Network) and the Massachusetts Computer Science Teachers Association are sponsoring a free, 3-day workshop for Massachusetts math and computer science teachers to explore the Bootstrap curriculum.  With Bootstrap, students ages 12-16 learn algebraic and geometric concepts through computer programming.  The workshop will be held February 16-18 at the Education Development Center, 43 Foundry Ave. in Waltham.  Space is limited, and applications are accepted first-come/first-served. Those who are interested but not math/computer-science teachers may email Kelly Powers (kelpowers@gmail.com) to explain their interest.  (Note:  This workshop is different from another free workshop, on Project GUTS, offered by MassCAN at the same time and same location.)
