Recent studies have revealed that making number-line estimates requires not only number knowledge but also a host of other cognitive skills. Here, we argue that a fundamental component of number-line estimation is the act of relating the target number being estimated to another numerical reference point (e.g., a previous estimate, the endpoint of the line) and then extending this relation to the spatial domain-in other words, that children recruit analogical reasoning skills when estimating… CONTINUE READING
