Strategies. Teacher's Guide.
San Francisco State Univ., CA.
This document is the second of seven units developed by the Math Network Curriculum Project. Each unit, designed to be a 2-week module, is a teacher's guide which includes detailed directions along with the courseware and software needed. Teacher intervention in the non-computer activities that begin each unit is required, and the consistent use of small-group instruction makes the units usable in a standard classroom if two microcomputers are present. Continuing the exploration of Easy Speak which students began in the Input-Output Unit, the Strategies Unit emphasizes discovering, inventing, and expressing in the Easy Speak language strategies for playing the game of Nim. At the beginning of the unit, students play Nim informally and then try to guess strategies which various computer programs use. The emphasis is not on finding one best strategy, but on discovering and inventing different kinds of strategies through pattern recognition and invention. Printed copies of the code for the Guess My Strategy, Nim Speak, Nim Rater, and Calendar Game computer programs are included. Guess My Strategy is a continuation of the attempt to guess the strategies used by the computer. Nim Speak allows students to teach the computer to play Nim using some strategy. With Nim Rater (written by Jerry Lane), students try for one of three ratings; they must win three games against the computer, which is using a perfect strategy. In the Calendar program (written by Lynne Alper and Bill Finzer), a variation of Nim, students take turns choosing dates later in the year; the one who arrives at December 31 wins. It thus challenges students who know the winning strategy for Nim. The programs were developed for use on a Commodore PET Computer with at least 16K of RAM using 4.0 BASIC. (MNS)
