Understanding Dyscalculia: Causes, Testing, and Remediation

Explore dyscalculia, a math learning disability affecting 5-8% of children, similar to dyslexia. Learn about its testing challenges, association with ADHD, and its links to genetics. Discover potential causes like bad teaching and anxiety, and how different brain regions impact mathematical abilities. Understand how children develop math skills through stages like counting and multiplication. Uncover remediation strategies to help individuals with dyscalculia succeed in math.

  1. Mathematics • (1 + x)n = 1 + nx + x2 +...+ xk +...+ xn. (1 + x)n = 1 + nx + x2 +...+ xk +...+ xn. (1 + x)n = 1 + nx + x2 +...+ xk +...+ xn. • (a + b)n = an + nan-1b + an-2b2 +...+ an-kbk +...+ bn,

  2. Dyscalculia Dyslexia of mathematics

  3. Who has it? • 5%-8% of 6-14 year olds have it • Similar to percent who have dyslexia • Children with siblings who have it are 5-10 more likely to also have it • 17% are also dyslexic • 25% have attention hyperactivity disorder

  4. How is it tested for? • There are no definitive tests for dyscalculia • Inconsistency in a child’s intellectual ability and their understanding of mathematics • Grasp of mathematics is consistent with a grade level two beneath the students

  5. Why can’t some people do math? Why can’t some people read? • Bad teachers • Only really intelligent people can do it • Anxiety • Phobia

  6. “We have an attitude that being bad at math is socially acceptable. People would never dream of telling others they are unable to read, will proclaim publicly they flunked math.”

  7. Different parts of the brain involved in different mathematical functions • Exact mathematics (language) left inferior frontal region • Approximate mathematics (visuo spatial cognition) Number sense bilateral parietal lobes

  8. Abstract vs. Exact • 1+1=2 • 7>3

  9. Innate math sense

  10. The Brain THE BRAIN

  11. Posterior parietal region of the brain that is active during arithmetic Is also responsible for goal directed hand movements

  12. How a child learns math • Birth • Counting • Adding/Subtracting • Multiplication/Division

  13. Remediation
