In this article, the author declares that if a student is able to discuss school math with family and friends just like one would a new movie, then that student has experienced meaningful math learning and teaching. With the support of the Social Sciences and Humanities Research Council, the author is presently working in K-8 classrooms, offering students opportunities to express their knowledge in words, pictures, concrete materials and symbols, as well as through the performing arts, using drama, music and dance. To help increase the repertoire of "math worth talking about," the Windows into Elementary Mathematics project was created at www.fields.utoronto.ca/mathwindows sponsored by the Fields Institute, where prominent mathematicians are invited to discuss topics from elementary mathematics. Each "Window" includes video clips of the mathematician, interactive content, a handout of activities, and a poster on the theme. The posters that accompany the Windows are available in digital form on the project website. The project also provides students, parents and teachers with insights into the thinking of mathematicians, and helps the public better appreciate the beauty of mathematics and mathematical ideas.
