Peer reviewedIkeda, Hitoshi; Ando, Masue – Arithmetic Teacher, 1974
Descriptors: Algorithms, Elementary School Mathematics, Instruction, Manipulative Materials
Peer reviewedCacha, Frances B. – Arithmetic Teacher, 1975
A modified method of regrouping the minuend for subtraction is described. This more flexible method decreases the number of steps in the subtraction process and in checking the regrouping. (SD)

Peer reviewedKratzer, Richard O.; Willoughby, Stephen S. – Journal for Research in Mathematics Education, 1973
Twelve fourth-grade classes in two schools were taught division using either the subtractive approach to the Greenwood algorithm or a partitioning approach to the standard algorithm. Analysis of class means on immediate, retention, and delayed retention tests indicated that use of the standard algorithm was more effective. (JP)

Peer reviewedQuast, W. G. – Arithmetic Teacher, 1972
A distinction is made between an algorithm and the justification for the algorithm. Examples of both are given for the operations with whole numbers. (DT)
