Discussing strategies for playing the mathematical game of "On Sets" are Mrs. Marc Ross and four Tappan Junior High students. David Sandalow and Clark Carrington are the students at left. Mark Plant is sitting on the desk. Next to him is Mary Beth Ogilvie. The Tappan students are among 15 junior-high pupils in the Ann Arbor Public Schools presently in training for the National Academic Games Olympics - a math tournament to be held April 24 to 26 in Ft. Lauderdale, Fla. At least five Ann Arbor students will compete. "On Sets" is a game about set theory and "new math", as can be seen from the symbols on the blackboard. Mrs. Ross is among several teachers helping to train the students for the nation-wide competition at the end of the month. (News photo by Jack Stubbs)
