Yanagimoto, Shigekazu – Focus on Learning Problems in Mathematics, 1999
Presents materials and methods that have been found to be effective in teaching addition and subtraction in specialized schools for the speech- and hearing-impaired. Concludes that there has been considerable success with students learning necessary mathematical skills by completing activities. Contains 11 references. (ASK)

Callahan, Leroy G.; Charles, Desiree – Focus on Learning Problems in Mathematics, 1985
Previous studies indicate that many early elementary school children have the misconception that whole number subtraction is a commutative operation. The degree and character of this subtraction error was investigated in this longitudinal study. Results obtained from three groups of students with different number abilities provided further…

deBettencourt, Laurie U.; Putnam, Ralph T. – Focus on Learning Problems in Mathematics, 1993
Compared use of derived fact strategies involving addition and subtraction by 20 learning-disabled students (LDSs) from an intermediate level self-contained class to 22 grade-3 normally achieving students (NASs). LDSs did not differ from NASs in verbal fluency or use of alternative strategies. (Contains 20 references.) (MDH)
