Peer reviewedMeyer, Ruth Ann; Riley, James E. – Mathematics Teacher, 1987
Suggested are investigations of rational numbers and their decimal representations where a computer generates the data for explorations. Conjectures and two program listings are included. (MNS)
Descriptors: Computer Software, Decimal Fractions, Discovery Learning, Investigations
Peer reviewedBeamer, James E. – Mathematics Teacher, 1987
Reported are several attempts to approximate Pi by using a microcomputer to calculate the ratio of the perimeter to the diameter of regular polygons enscribed in a circle. Three computer programs are listed. (MNS)

Peer reviewedBledsoe, Gloria J – Mathematics Teacher, 1987
The game of "Guess What" is described as a stimulating vehicle for students to consider the unifying or distinguishing features of geometric figures. Teaching suggestions as well as the gameboard are provided. (MNS)
Descriptors: Educational Games, Geometric Concepts, Learning Activities, Lesson Plans
Peer reviewedAtkinson, David – Mathematics Teacher, 1987
A proof of the conic sections of an ellipse is presented. (MNS)
Descriptors: Geometric Concepts, Mathematics, Mathematics Instruction, Proof (Mathematics)
Peer reviewedMovshovitz-Hadar, Nitsa; And Others – Mathematics Teacher, 1987
A lesson in editing was learned from a study of errors made on a national mathematics test in Israel. Analysis indicated that the errors were often caused by careless printing of the test, misleading figures, poor designations, or ambiguous phrasing. (MNS)
Descriptors: Error Patterns, Mathematics Achievement, Mathematics Instruction, Secondary Education
Peer reviewedBecker, Jerry P.; Yi-Yun, Zhou – Mathematics Teacher, 1987
University entrance examinations in China are described. Then the 1985 test is presented. (MNS)
Descriptors: College Mathematics, Higher Education, Mathematics Instruction, Testing
Peer reviewedFolio, Catherine – Mathematics Teacher, 1987
An activity involving the charting of the spread of a disease is described. Arrows are used to develop models of the progression of the disease. (MNS)
Descriptors: Grade 7, Graphs, Grouping (Instructional Purposes), Learning Activities
Peer reviewedPerez, Ricarda A.; And Others – Mathematics Teacher, 1987
Brief articles concern solving a polynomial equation of degree greater than two, an approach for teaching an ambiguous case in trigonometry, and built-in functions on calculators and computers. Two computer programs are listed. (MNS)
Descriptors: Algebra, Computer Software, Equations (Mathematics), Functions (Mathematics)
Peer reviewedLappan, Glenda; And Others – Mathematics Teacher, 1987
The activity uses an area model to analyze probabilities associated with games of chance. Three activity sheets are included, with teaching suggestions. (MNS)
Descriptors: Instructional Materials, Learning Activities, Mathematical Models, Mathematics Instruction
Peer reviewedMansheim, Jan; Baldridge, Phyllis – Mathematics Teacher, 1987
How set theory, combinatorics, probability, and the study of algorithms can be used in solving two problems is described in detail. Three computer programs are listed. (MNS)
Descriptors: Algorithms, Computer Software, Flow Charts, Learning Activities
