An investigative activity dealing with where to pitch a tent at a campsite is described. (MNS)

An activity sequence is described. Several aspects of a population problem are developed using isoperimetric graph paper and symmetry principles to derive general rules. (SD)

Definitional questions are raised first, followed by discussion of simulations and their place in the mathematics classroom. Variety and classification are discussed, plus some comments on designing simulations. (MNS)

Lessons on using maps to look for a new home are described. Data collectd from a questionnaire were compared by the students. (MNS)

Some specific uses of microcomputers in mathematics instruction are presented. Included are examples for generating data and patterns, checking, practice of various types, developing understanding, comparing results, simulation of experiments, introducing new ideas, solving problems, and extending into new areas. Brief computer programs are given.…
