Wayland Patch 6/27/11: School Committee Members Learn about Math Preview Strategy. During the past school year, 35 kids at Wayland’s Claypit Hill and Happy Hollow elementary schools made it a point to stay after school once a week for sneak previews. With that kind of commitment, you’d expect they were previewing the newest Pixar film or Harry Potter book, but in fact, they were previewing their upcoming math lessons. Aidan McCann, a fourth grade teacher at Claypit, piloted a math preview strategy during the 2010-11 school year. The strategy was designed to give students with a math focus on their Individualized Education Programs (IEPs) a chance to gain confidence and understanding of the unit’s math concepts before those concepts were introduced during regular classroom lessons.
