Discusses the geometric and mathematical features of the pyramids in Cairo. Describes the relationship between the great pyramid and Pi. (ASK)

An activity for generating approximations of pi is described. (MK)

Demonstrates some of the usefulness of number theory to students on the high school setting in four areas: Fibonacci numbers, Diophantine equations, continued fractions, and algorithms for computing pi. (ASK)

Presented with appropriate formulas and illustrations are five lessons suitable for college mathematics undergraduate students, including Pi and the limit of (sin alpha)/alpha, the structure of orthogonal transformations, a simple proof of Zorn's Lemma, the converse of Liouville's Theorem, and visualizing the p-adic integers. (JJK)

Techniques for estimating pi using the microcomputer are demonstrated. Four BASIC programs, coded from pi generating formulas, are compared for efficiency. (PK)

Three experiments which use probabilities to approximate pi are described. (JT)

A sequence of activities leading to the concept of Pi is suggested. (DT)

This book is a guide for parents and teachers of mathematically talented elementary school students. Chapters and sections include: (1) "Overview"; (2) "Historical and Current Perspectives"; (3) "Making Informed Educational Decisions"; (4) "Diagnostic Testing Followed by Prescriptive Instruction: SMPY's DT to PI Model"; (5) "Mathematics Curriculum…

One schools' experiences with mathematics contests are described, with American Pi, the Great Calculator Contest, and the Forest View Math Olympics in problem solving each detailed. (MNS)

References to approximations of pi in the Bible and calculations of pi in the Egyptian Phind Papyrus are noted, followed by a finding of an eighteenth-century Polish rabbi about the exactness of the Biblical computation. (MNS)

Diagrams that aid in relating the golden ratio to pi are discussed, with the theorem and its proof. (MNS)

A computer simulation of the Buffon Needle Problem for estimating the value of pi is discussed. (MP)

An activity is described in which PI is approximated by measuring the perimeters of regular polygons inscribed in a unit circle. (DT)

Gives a lesson plan for a mathematics activity using balloons which shows connections between the algebraic concepts of slope, linear functions, and power functions and the geometric concepts of circle, sphere, volume, and pi. Includes reproducible student worksheets. (MKR)

Presents an algorithm to estimate pi by approximating a unit circle with a sequence of inscribed regular polygons. Demonstrates the application of the algorithm with a hand-held calculator and an Apple computer. Provides a program to calculate pi in Pascal programing language. (12 references) (MDH)
