Abstract

A group of preservice teachers could not recall or devise criteria for determining when 7 (or any higher prime) divides N. Tests for divisibility, a topic once studied by students, seems to have disappeared from the curriculum, with teachers themselves having only a pedestrian knowledge of this topic. This paper presents several different ways to construct tests of divisibility for low valued divisors.
