Sass, Louis, Jr. – MATYC Journal, 1975
Descriptors: College Mathematics, Computation, Higher Education, Mathematics Education
Peer reviewedBright, George W. – Arithmetic Teacher, 1978
Two ideas to use as a bulletin board display as an activity center, or as worksheets emphasizing whole number concepts are described. (JT)
Descriptors: Computation, Elementary Education, Elementary School Mathematics, Learning Activities
Peer reviewedPagni, David L. – Mathematics Teacher, 1979
The concept of prime factorization is discussed and two rules are developed: one for finding the number of divisors of a number and the other for finding the sum of the divisors. (MP)
Descriptors: Algorithms, Computation, Instruction, Mathematical Formulas
Peer reviewedThornton, Chich – Australian Mathematics Teacher, 1985
Some benefits of helping learners think in prime numbers are detailed. Reasons for the decay of this ability are described, with short division presented as one activity which should be reintroduced in schools. (MNS)
Descriptors: Computation, Division, Elementary Education, Elementary School Mathematics
Peer reviewedJoyner, Virginia G.; Haggard, Paul W. – Mathematics and Computer Education, 1990
Discusses how to express an n factorial as a product of powers of primes. Provides two examples and answers. Presents four related suggestions. (YP)

Toth, Frank S., Jr. – Computing Teacher, 1979
This calculator experiment for seventh-grade students on prime factorization contains objectives, difficulties, a discussion, several examples, and a worksheet. (MP)

Peer reviewedAnderson, Mike; O'Connor, Neil; Hermelin, Beate – Intelligence, 1998
Studied the calculating ability used by a low IQ savant to identify prime numbers in two experiments comparing him to control subjects, one involving reaction time and the other involving inspection time. Concludes that this individual uses a complex computational algorithm to identify primes and discusses the apparent contradiction of his low IQ.…

Peer reviewedWelling, Hans – Journal of Autism and Developmental Disorders, 1994
The ability of some individuals with mental retardation to identify prime numbers despite their lack of necessary arithmetical skills is discussed. The article suggests that a distinction between prime and nonprime numbers can be made by utilizing the tendency of visual perception to be symmetrically organized. (Author/DB)
Descriptors: Abstract Reasoning, Computation, Exceptional Persons, Mathematics
Peer reviewedLevine, Deborah – Mathematics and Computer Education, 1983
The Euclidean algorithm for finding the greatest common divisor is presented. (MNS)
Descriptors: Algorithms, College Mathematics, Computation, Higher Education
Peer reviewedGardiner, Tony – Mathematics in School, 1990
Proposed is a way for teachers to distinguish between rich, challenging material that encourages mathematical thinking and material that is unsuitable. Included are multistep problems that encourage a broader understanding of mathematics. (KR)

This book is intended to make common seventh-grade mathematical concepts both interesting and easy to understand. The text is designed to meet the particular needs of those children who have "accumulated discouragements" in learning mathematics. The reading level required of pupils has been reduced. Individual chapter titles are: The…
