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 reviewedJansson, Lars C. – Arithmetic Teacher, 1974
This article explains the generation of Kaprekar's constant in terms that upper elementary pupils can understand. The procedure is explained and the result proven. This is an example of a new, interesting problem for students that gives them drill in subtraction at the same time. (LS)
