Hirsch, Christian R. – Mathematics Teacher, 1974
A series of activities are presented on worksheets marked off with lattice points (like a geoboard). Students are led to discover and apply Pick's Theorem for finding the area of a polygon whose vertices are lattice points. (JP)

Hirsch, Christian R. – Mathematics Teacher, 1975
Using a set of worksheets, students will discover and apply Euler's formula regarding connected planar graphs and play and analyze the game of Sprouts. One sheet leads to the discovery of Euler's formula; another concerns traversability of a graph; another gives an example and a game involving these ideas. (Author/KM)

Nelson, Barbara A.; Frayer, Dorothy A. – 1972
This study was designed to investigate the effects of discovery and expository methods of presentation on the immediate acquisition and retention of geometry concepts by seventh graders. Four geometry concepts, "quadrilateral,""rhombus,""trapezoid," and "parallelogram," were presented in written lessons which used either an expository or a…

Ranucci, Ernest R. – Mathematics Teacher, 1974
To discover a generalization from a pattern of data, students need to know how to analyze the data. This is a description of how high school students can find a formula to predict the number of spherical fruits in a piling by using differences. (JP)
