Peer reviewedBoas, R. P., Jr. – Two-Year College Mathematics Journal, 1972
The problem of getting a correct result when a fraction is reduced by cancelling a digit which appears in both the numerator and the denominator is extended from the base ten situation to any number base. (DT)

Peer reviewedEttline, J. Fred – Arithmetic Teacher, 1985
Two difficulties that students have in computing with fractions are idenfitied. Then a procedure is described, stressing the identity element, that resolves these difficulties and increases students' understanding and retention. (MNS)

Hector, Judith H. – 1978
The relative effectiveness of three methods of teaching fraction computation in the context of the community college was investigated. The use of calculators was a special focus of the study. The three methods were: (1) conventional algorithms with no calculator, (2) conventional algorithms with calculator, and (3) alternative algorithms using…

Talton, Carolyn – Illinois Mathematics Teacher, 1997
Illustrates how upper elementary grade students can develop an understanding of the invert-and-multiply algorithm. (CCM)
Descriptors: Algorithms, Arithmetic, Elementary Education, Fractions
Peer reviewedCohen, Israel – Mathematics Teacher, 1974
A method for generating Pythagorean triples is presented and demonstrated with several examples. Its relationship to another method is shown and several interesting related facts are proven. (LS)

Carney, Harold Francis – 1973
The purpose of the study was to compare the results obtained from a group of fourth-grade students taught to add and subtract rational numbers through the use of field postulates and other properties of whole numbers with fourth-grade students taught by a standard method using objects and the number line. Eight classes of 30 students each…
