Ron loves coddiwompling and he sees mathematics everywhere he walks. He never leaves home without his pair of math glasses and camera so that he is always ready to snap photos of numbers, patterns, shapes, solids, curves and shadows. Throughout his career, Ron has made connections between the mathematics curriculum and daily life in an effort to help students appreciate and enjoy mathematics.
Ron is well known for his expertise in designing Math Trails. Ron has created these math paths in many locations around the world including Singapore, where thousands of students and hundreds of teachers have enjoyed his walks in Suntec City, Fort Canning Park and the NUS Art Museum. Ron has developed Math Trails in Manhattan for Math for America, the Avenues School and the Museum of Mathematics at many locations in the city.
