Jones Distinguished Teaching AwardÔ e ah Ha moment Well designed problem solving episodes oen elicit such moments from a broad range of audiences ranging from secondary students , to mathe- matics majors, and to inservice teachers; for example, the nice Ôýth grade problem: How many positive integers are there whose digits are in strictly increasing order (like ò¥Þ)? has an unexpected ah ha moment.
