Dale Ray Rapp Dale Ray Rapp 87, of Duluth, MN, died Sunday June 27, 2021, at Essentia Health Miller-Dwan Hospital Duluth, after a valiant battle with cancer. Dale was born in Duluth, Minnesota, September 6, 1933 to George and Gladys Rapp, the third of four boys. He was raised on 43rd Avenue West, one block from Denfeld High School, where he graduated with honors. Dale went on to the University of Minnesota-Duluth, receiving B.A., M.A. and Ed.S. degrees in education. While in college, he married Carole Westman, and together they raised three children. Dale’s love for education and natural teaching ability led to a 30-year career as a math teacher-- from 1962-1992--primarily in the Duluth School District, serving many years at Washington Junior and Central Senior High Schools. Dale distinguished himself in the field of education, continually seeking to engage students and make learning fun. As proof of this, in the mid-1960’s he developed the “Arithmetic Fact Kit”, published by Science Research Associates (SRA). It was fun, challenging, and became the “official math kit” used by school districts throughout the United States.
