Description

This data is from a larger project, the Study of Language and Math, at the University of Connecticut. It consists of children's (ages 5-9) performances on our mapping task that assessed their ability to translate between three number representations: Arabic numerals, number words, and quantities (e.g., dot arrays). We analyzed children's performance on different mappings and set sizes (measured by proportion correct) across three age groups: 5-years-old, 6-years-old, and 7 to 9-years-old. 5-year-olds showed the most variability in overall performance and set size effects, performing best on numeral-word mappings and equivalently on quantity-numeral and quantity-word mappings. Children 6 years old and older barely had any set size effects and performed equally well on numeral-word and quantity-numeral, but remained less skilled at mapping among quantities and words.
