Abstract:
Students analyze a photograph to solve mathematical questions related to the images captured in the photograph. This month's photographs are all examples of triangular numbers occurring in the marketplace or other real world locations. The mathematics involves finding and verifying formulas for special triangular numbers. Edited by Ron Lancaster and Brigitte Bentele.
