Peer reviewedSgroi, James T. – Mathematics Teacher, 1977
Patterns that appear in the repeating digits of a decimal are used to help convince students that any infinite repeating decimal can be written in the form of a rational number. (JT)
Descriptors: Decimal Fractions, Fractions, Instruction, Pattern Recognition
Peer reviewedWagner, Sue S. – Mathematics Teacher, 1979
This discussion of cyclic patterns that appear in repeating decimals includes the use of the calculator in discovering the patterns. (MP)

Peer reviewedMcGinty, Robert L.; Mutch, William – Mathematics Teacher, 1982
Repeating decimals are used as a source for geometric patterns. Ways for generating patterns focus on dividing a circle into certain numbers of equal parts and interpreting the decimal expansions of certain fractions in terms of connecting sequences of points. Suggestions for possible expansions are given. (MP)

Peer reviewedBell, Garry – Australian Mathematics Teacher, 1991
Mechanical devices offer an alternative to computers to explore mathematical concepts in different curricula areas. Described is the discograph, a series of pulleys and wheels, that can be used to teach mathematical principles in pattern drawing, locus, rotation in geared systems, gearing, rotational symmetry, regular plane figures, decimal, and…

Immerzeel, George, Comp.; Thomas, Melvin, Comp. – 1982
This compilation is drawn from the IDEAS section that has been a feature of the "Arithmetic Teacher" since 1971. The contents are arranged in the following categories: Computation, Fractions and Decimals, Developing Number Patterns, Using Flowcharts, Problem Solving, Geometry, and Metric Measure. All selections are reprinted just as they…

Schwartzman, Steven – MATYC Journal, 1976
Patterns in decimal expansions are investigated. (DT)
Descriptors: College Mathematics, Decimal Fractions, Higher Education, Instruction
Peer reviewedCusumano, Andrew – AMATYC Review, 1992
Discusses 4 numerical patterns occurring in the decimal expansions of 2 raised to a negative exponent. Includes two row patterns, one diagonal pattern, and a pattern in the sum of the digits of the expansions. Conjectures are presented for each pattern and subsequently proved. (MDH)

Power On! Promoting Classroom Dialogue: Using Calculators to Discover Patterns in Dividing Decimals.
Peer reviewedWilliams, Susan E.; Copley, Juanita V. – Mathematics Teaching in the Middle School, 1994
Discusses the collaboration between a university and local school district in the use of calculators to help students discover patterns and to estimate quotients when dividing decimals. (MKR)
