Ron Lancaster, Jim Sandefur 

May 2005, Volume 98, Issue 9, Page 637


Photograph is of a speedometer and odometer with target questions focused on mathematical topics that include palindromes and number patterns. Mathematical Lens uses photographs as a springboard for mathematical inquiry. The goal of this department is to encourage readers to see patterns and relationships that they can think about and extend in a mathematically playful way. Mathematical Lens is a regular department of Mathematics Teacher. Students analyze a photograph to solve mathematical questions related to the images captured in the photograph.
