Lockwood, Elise – North American Chapter of the International Group for the Psychology of Mathematics Education, 2013
Counting problems have applications in probability and computer science, and they provide rich contexts for problem solving. Such problems are accessible to students, but subtleties can arise that make them surprisingly difficult to solve. In this paper, students' work on the Groups of Students problem is presented, and an important issue related…
