S ummary . 44 children from an ESN school were pre‐tested on Piaget‐type tasks involving conservation of weight. From these, two matched groups, each of six children (age 13 to 15, mental age 7 to 11) who consistently gave non‐conservation responses, were selected. One group was given an individual teaching session of 15 to 30 minutes involving various tasks, manipulations and explanations. Post‐tested after two and four weeks, all six showed consistent conservation of weight, whereas none of the controls did so. The six controls were then given comparable teaching, with similar positive results. Eight months later, 11 of the 12 children were re‐tested and showed consistent conservation of weight. Results suggested that what they had learned about weight was readily generalised to volume.
