Measurement in the perspective of number sense in children
This study investigates children's knowledge about measurements based on the idea of invariants, and of number sense. Forty children (6 and 8 years old) made judgments about situations involving measurements of volume, time, mass, distance and length. Task 1 examined the ability to identify the appropriate unit to measure different objects, and Task 2 the understanding of the inverse relation between the size of the unit and the number of units needed to measure something. Results showed that children have a sense of measurement and that this sense does not manifest itself equally in relation to different types of measurements. Also, children showed a better understanding about the inverse relation between the size of the unit and the number of units than of the relation between unit and object to be measured.
