How Children with Learning Problems Learn Addition: A Longitudinal Study.
Hanrahan, James; And Others
Canadian Journal of Special Education, v9 n2 p101-09 1993
Seventy-seven children (ages 5-13) with mild to moderate mental retardation were presented with addition problems. The patterns of strategies used were found to be similar to those used by intellectually normal children, though counting-on and memory strategies were used by subjects with greater frequency. Strategies became more sophisticated with subjects' age. (Author/JDD)
