THE ROLE OF NUMBER SENSE IN CHILDREN'S ESTIMATING ABILITY

This paper presented findings of a study looking at the comparative and combined effects of age and number-sense on children 's ability to estimate measures. While evidence was found for a developmental effect of age on children 's number-sense, no such effect was found for the ability to estimate either length or area. However, childrens ' ability to use and perceive number relations, together with an understanding of the relative magnitudes of larger numbers, were found to have a significant influence on their ability to estimate area
