 FEATURES Early Secondary Mathematics: Teaching Sums of Angle Measures: A Kinesthetic ApproachAyana Touval, Galeet WestreichA different approach to teaching students how to measure the sums of angles of various polygons. They employ kinesthetic activities with easy-to-follow diagrams and instructions and provide activity sheets for recording activity experiences. Mathematical Insight: Changing PerspectiveCliff SloyerA number of examples to demonstrate how looking at solutions to problems from different perspectives can enrich a students' problem solving skills. Birthday LiesDale HathawayHow potentially dishonest students can affect the classic birthday problem. Penny Packing for Your ThoughtsStanley Bezuszka, Margaret KenneyThis article pursues a well-known mathematical problem at an introductory level and from a standpoint that is within reach of students involved in algebra and geometry. The Play-off Probability ProblemMurray LauberThis article builds on a classroom-generated solution to explore, to compare, and to generalize, a number of approaches to the problem of determining the probability of a team winning a playoff series. A Problem-Posing Approach to Specializing, Generalizing, and Extending Problems with Interactive Geometry SoftwareJosÃ© ContrerasHow to use a problem-posing model and dynamic geometry software for formulating problems and conjectures within geometric contexts. Where Is the Highest Point on the Roof of a Shed?Ysbrand de BruynA geometric model, which can be used to enlighten the basic concepts of linear programming, and provides a visual way of understanding the simplex methods of linear programming.
