Abstract
Twenty-six children from Years 5 to 8 were given a task-based interview on fraction knowledge. The verbal responses of the children to three tasks out of the 35 offered are discussed in depth here. The use of measurement and spatial language was evident in correct and incorrect answers. What was more critical were misconceptions about understandings of measurement principles. The rational number domain with its infinite number of points between any two fractions can be seen as more like the measurement domain where continuous properties are measured, than the whole number domain where discrete items are counted. This analogy may be useful for children?s conceptual understanding of fractions.
