Abstract
An earlier study analysed responses by 70 young children to a variety of multiplication and division word
problems at four interview stages in a 2-year longitudinal study (Mulligan,· 1992). 75% of the children were·
able to solve the problems using a wide variety of counting, grouping and modelling strategies· and the
semantic structure of the problem strongly influenced solution process. A follow up study Was conducted with
the same sample (n=45) in Grade 6, prior to entry to secondary school. Identical problem structures were
used including problems involving decimals, A similar pattern of performance to the longitudinal study
revealed a 60-85% success rate except for Sub-division, and poorer results for decimal problems. Informal
methods used by children in the. early stages of the study dominated their understanding. of multiplicative.
structures in Grade 6. Evidence of children's lack of conceptual understanding o/multiplication and division
was revealed.
