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 is one in a series of SMSG supplementary and enrichment pamphlets for high school students. This series makes available expository articles which appeared in a variety of mathematical periodicals. Topics covered include: (1) the history of the number pi; (2) what's new about pi; (3) the number pi; (4) pi and probability; and (5) from the…

This is one in a series of SMSG supplementary and enrichment pamphlets for high school students. This series makes available expository articles which appeared in a variety of mathematical periodicals. Topics covered include: (1) the latest about pi; (2) a series useful in the computation of pi; (3) an ENIAC determination of pi and e to more than…

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

Approximating the limits of certain convergent series is discussed as a method for students to use in calculating an approximation for pi. (FL)

Using license plates to generate random number pairs, students can calculate an approximate value for pi. The author views this approach as easier to understand than Buffon's needle. (SD)

A collection of mathematical notes - On the Roots of a Certain Determinantal Equation", A Geometrical Look at the Square Root of Pi", and others. (RP) A class of Second Order

Euler's famous formula, e to the (i, pi) power equals -1, is developed by a purely algebraic method that avoids the use of both trigonometry and calculus. A heuristic outline is given followed by the rigorous theory. Pedagogical considerations for classroom presentation are suggested. (LS)

Contained in this column are articles discussing the following topics: cross-number puzzles, an intuitive development of pi, a three-column proof format, and an easily constructed kit to be used in acquainting students with the wrapping function used in introducing circular functions. (MP)

This publication contains the substance of all papers submitted at the fall 1974 Association of Teachers of Mathematics in New England (ATMNE) conference. As the title indicates, the focus of the publication is directed toward mathematical applications. The 25 papers cover topics ranging from applications at the elementary school level to those…

The 26 activities described in this volume deal with a wide variety of mathematical ideas. Most of the activities are appropriate for grades 6-9; many could be used with older or younger groups as well. All activities are described in detail; some descriptions include sample worksheets, and several provide suggestions for followup activities. The…
