Without math fact automaticity, working memory may be taxed when doing computation, and the child “loses his place” in the problem while computing each part to arrive at a final answer. Difficulty with retrieval of math facts is a weakness/deficit associated with math LDs (Geary et al., 2007 Gersten, Jordan, & Flojo, 2005). Math fluency refers to how quickly and accurately students can answer simple math problems without having to compute an answer (i.e., from memory 6 x 6 = 36), with no “steps”, calculation, or number sense needed.Ĭhildren with fluency deficits often use immature counting strategies and often do not shift from computation to storing and retrieving math facts from memory, taking more time to provide an answer. Math FluencyĬhildren often rely on various strategies when solving simple calculation problems, but math computation requires caring out a sequence of steps on paper or in your mind (working memory) to arrive at an answer. Poor early number sense predicts math LDs in later grades (Mazzocco & Thompson, 2005). Children link basic number sense to symbolic representations of quantity (numbers) the math “language”. These basic math skills include understanding of number magnitudes, relations, and operations (e.g., adding). Number Sense / Numerical KnowledgeĬhildren develop knowledge of quantity even before math instruction in schools, and kindergarten number sense is predictive of math computation and problem solving skills in elementary school (Jordan et al., 2010). Let’s first explore the fundamental skills needed for math achievement. You might be surprised to learn that approximately 7% of school-aged children have a LD in mathematics (Geary, Hoard, Nugent, & Bailey 2012). Math is a language with symbols that represent quantity facts instead of language facts (i.e., vocabulary), so rules (syntax) are important for both (Maruyama, Pallier, Jobert, Sigman, & Dehaene, 2012). Similarly, the old belief that reading is a left brain task, and math is a right brain task, is not a useful dichotomy as clearly multiple shared and distinct brain regions explain these academic domains (e.g., Ashkenazi, Black, Abrams, Hoeft, & Menon, 2013). The old belief – boys are naturally better at math than girls – may be more a consequence of teacher differences or societal expectations than individual differences in math skill (Lindberg, Hyde, Petersen, & Linn, 2010). Some love it, some loathe it, but there are many myths about math achievement and math learning disabilities (LDs).
