Some Lessons

Abstract

Let me begin with an anecdote about two ten year old boys demonstrating various skills in a game of “Multiplication Snap” (Brown, 1994 c). Each had a share of playing cards and took turns to place a card on a central pile. My understanding of the teacher’s intention was that if the product of two successive cards was in the range twenty to forty the first person to say “snap” collected the central pile. The game finished when one player ran out of cards.
