Mental number line, number line estimation, and mathematical achievement: their interrelations in grades 5 and 6.
As indicated by the distance effect and the spatial–numerical association of response codes
(SNARC) effect, natural numbers are mentally represented on a number line. Purportedly,
this number line underlies children's number sense, which supports the acquisition of more
advanced mathematical competencies. In 3 studies with a total of 429 fifth and sixth graders,
the authors compared the influences of each child's distance effect, SNARC effect,
conceptual knowledge about decimal fractions, and numerical intelligence on mathematical …
