Windows

Abstract

A group of teachers took a walk around their school and began to notice the different window arrangements on apartment buildings and business complexes in the community. The structures had different window groupings, different numbers of window panes—depending on a building's size and design—and different numbers of windows to a side. The teachers later collaborated to develop an activity that would offer students opportunities to count, work in groups, and develop their multiplicative thinking skills. The windows provided the context for the investigation.
