Zooming-in on Decimals
Gorman, Amelia; Way, Jennifer
Mathematics Education Research Group of Australasia, Paper presented at the Annual Meeting of the Mathematics Education Research Group of Australasia (MERGA) (41st, Auckland, New Zealand, 2018)
This study investigated how six Year Four (9-10 years old) students interacted with a dynamic (zoomable) digital number line to demonstrate knowledge and understandings of decimal fractions. Results from a task-based interview indicated that the zoomable number line is able to assist students in developing conceptual understandings of decimal density, place value and relative size. The app proved to be a powerful mathematical representation of decimal fractions because of its dynamic affordances that allowed the students to 'see' concepts that would otherwise be 'unseeable' when using a traditional static number line.
