Number Guessing
Sezin, Fatin
Australian Mathematics Teacher, v65 n3 p10-16 2009
It is instructive and interesting to find hidden numbers by using different positional numeration systems. Most of the present guessing techniques use the binary system expressed as less-than, greater-than or present-absent type information. This article describes how, by employing four cards having integers 1-64 written in different colours, one can guess the secret number held by the player. This game can be used as a teaching aid for demonstrating base-4 representation of numbers or the concept of isomorphism. (Contains 4 figures.)
