“…Mathematical development is related to domain specific cognitive processes (cognitive processes that are specific to mathematics), as well as broad cognitive processes such as working memory, language, and reasoning (Fuchs et al, 2010). Domain specific cognitive processes include: Subitizing or numerosity (i.e., the ability to automatically and accurately determine the quantity of sets of up to three or four items; Wynn, Bloom, & Chiang, 2002); magnitude estimation (i.e., the inexact, but quick estimation of quantities larger than 3 or 4; Pica et al, 2004); ordinality (i.e., understanding of the concepts "more than" and "less than"; Feigenson, Carey, & Hauser, 2002); counting (i.e., understanding of counting principles such as one to one correspondence; Gelman & Gallistel, 1978); arithmetic sensitivity (i.e., sensitivity to increases and decreases in the quantity of small sets of items; Kobayashi, Hiraki, Mugitani, & Hasegawa, 2004); and geometry (i.e., basic understanding of spatial relations; Dehaene, Izard, Pica, & Spelke, 2006).…”
