The School Mathematics Study Group (SMSG) ' courses have Been taught at Downers Grove High School for the last three years. In the modern ap- proach to math, these classes give instruction which consists of explaining algebra and geometry in terms of set theory. This year two new courses were added to the math curriculum: in the first of; the new classes, seniors who had taken algebra in i the eighth grade, were taught principles of finite math and calculus; in the second program juniors and seniors who had completed three years of SMSG math were taught advanced ideas in set1 theory. 16
