  2. Understanding Dyscalculia Definitions of Dyscalculia No universal definition (a few samples) • An unexpected difficulty that some people have in dealing with mathematical problems (Attwood) • A condition that affects the ability to acquire arithmetic skills (The British Dyslexia Association, www.bda-dyslexia.org.uk) • Having huge problems in math, in spite of being of normal intelligence (www.dys.dk)

  3. Understanding Dyscalculia Definitions of Dyscalculia • Difficulties in performing mathematics calculations of certain types (www.dyscalculiainfo.org) • A term referring to a wide range of life-long learning difficulties involving math. There is no single form of math disability, and difficulties vary from person to person and affect people differently in school and throughout life. (www.ld.org)

  4. Understanding Dyscalculia Diagnostic Criteria for Mathematics Disorder(Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, American Psychiatric Association) • Mathematical ability, as measured by individually administered standardized tests, is substantially below that expected given the person’s chronological age, measured intelligence, and age-appropriate education. • The math difficulties significantly interfere with academic achievement or activities of daily living that require mathematical ability. • If a sensory deficit is present, the difficulties in mathematics ability are in excess of those usually associated with it.

  5. Understanding Dyscalculia Skills Impaired in Mathematics Disorder (Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, American Psychiatric Association) • “Linguistic” skills: understanding or naming mathematical terms, operations, or concepts, and decoding written problems into mathematical symbols • “Perceptual” skills: recognizing or reading numerical symbols or arithmetic signs and clustering objects into groups • “Attention” skills: copying numbers or figures correctly, remembering to add in “carried” numbers, and observing operational signs • “Mathematical” skills: following sequences of mathematical steps, counting objects, and learning multiplication tables

  6. Understanding Dyscalculia Underlying Causes(www.ldonline.org) • Visual-spatial difficulties-trouble processing what the eye see • Weakness in visual processing of numbers and mathematical situations • Auditory processing difficulties- trouble processing and making sense of what the ear hears.

  7. Understanding Dyscalculia Underlying Causes (www.ldonline.org) • Attention deficits • Memory problems • Information processing deficits • Motor disabilities • Problems with sequencing, organizing information • Problems with understanding concepts and symbols

  8. Understanding Dyscalculia Prevalence of Dyscalculia • 5-8% of school age children (Strauss, 2003) • 3-6% of population (www.bda-dyslexia.org) • 6-7% of school age children (www.ldonline.org) • 1% of all children (www.dys.dk) • 1% of all school age children have Mathematics Disorder (DSM-IV-TR, 2000) • 5-6% of all children (Adler, 2001)

  9. Understanding Dyscalculia Symptoms or Warning Signs by Age Young Children (www.ld.org) • Difficulty with number sense • Difficulty learning to count • Trouble recognizing printed numbers • Difficulty with connecting the idea of a number with what it represents in the real world

  10. Understanding Dyscalculia Symptoms or Warning Signs by Age Young Children (www.ld.org) • Poor memory for numbers • Trouble organizing things in a logical way, sorting by shape, size, color, etc. • Trouble recognizing groups and patterns • Trouble comparing and contrasting, smaller/larger, taller/shorter

  11. Understanding Dyscalculia Symptoms or Warning Signs by Age School Age Children (www.ld.org) • Trouble learning math facts • Difficulty developing math problem solving skills • Poor long term memory for math functions • Not familiar with math vocabulary • Difficulty with measuring things

  12. Understanding Dyscalculia Symptoms or Warning Signs by Age School Age Children (www.ld.org) • Avoiding games that require strategy • Visual-spatial difficulties hinder comprehension of written mathematics • Difficulties reading a clock • Problems with time perception, leads to problems with planning time required to complete a task

  13. Understanding Dyscalculia Symptoms or Warning Signs by Age Teenagers and Adults (www.ld.org) • Difficulty estimating cost (shopping, groceries) • Difficulty learning math concepts beyond basic math facts • Poor ability to budget or balance a checkbook • Trouble with concepts of time, such as going by a schedule or approximating time

  14. Understanding Dyscalculia Symptoms or Warning Signs by Age Teenagers and Adults (www.ld.org) • Trouble with mental math • Difficulty finding different approaches to one problem • Trouble with visualizing patterns, different parts of a math problem or identifying critical information needed in problem solving

  15. Understanding Dyscalculia Signs That Difficulties With Math are Beyond “Normal” (www.ld.org, www.as.wvu.edu, www.dyscalculia.org) • Good in verbal skills, but difficulty with math skills • Good memory for printed words, but difficulty reading numbers or recalling numbers in sequence. • Good with general math concepts, but frustrated when specific computation or organization skills need to be used.

  16. Understanding Dyscalculia Signs That Difficulties With Math are Beyond “Normal” (www.ld.org, www.as.wvu.edu, www.dyscalculia.org) • Trouble with the concept of time: late, doesn’t remember schedules, can’t approximate how long a task will take, confused on past/future events • Poor sense of direction, confusion on left/right orientation • Easily disoriented and easily confused by changes in routine

  17. Understanding Dyscalculia Signs That Difficulties With Math are Beyond “Normal” (www.ld.org, www.as.wvu.edu,www.dyscalculia.org) • Poor long term memory, will know math facts one day, not remember the next • Fails to see big financial picture • History of academic failure contributing to the development of learned helplessness in mathematics

  18. Understanding Dyscalculia Strategies to Help Students with Dyscalculia (www.ldonline.org, www.ld.org, www.as.wvu.edu) • First step must be to identify a student’s strengths and weaknesses, understand how a student learns best • Use tutoring outside the classroom, with a one-on-one instructor • Provide a distraction free place to work • Encourage repeated reinforcement and specific practice

  19. Understanding Dyscalculia Strategies to Help Students with Dyscalculia (www.ldonline.org, www.ld.org, www.as.wvu.edu) • Use graph paper to organize work and ideas • Use different approaches to memorizing math facts, formulas, rules, etc. • Practice estimating as a first step to solve a problem • Encourage students to work hard to “visualize” math problems, draw pictures, look at diagrams, etc.

  20. Understanding Dyscalculia Strategies to Help Students with Dyscalculia (www.ldonline.org, www.ld.org, www.as.wvu.edu) • Encourage verbalizing while problem solving, this uses auditory skills which may be a strength • Try to relate problems to real life experiences • Provide uncluttered worksheets, preferably lined • Use rhythm or music to help memorize math facts, etc.

  21. Understanding Dyscalculia Strategies to Help Students with Dyscalculia (www.ldonline.org, www.ld.org, www.as.wvu.edu) • If possible, let student take tests one-on-one in the instructors presence. • Allow extra time to complete work if needed • Be aware if students become panicky, provide reassurance • Monitor student progress on a frequent basis

  22. Understanding Dyscalculia Strategies to Help Students with Dyscalculia (www.ldonline.org, www.ld.org, www.as.wvu.edu) • Teach important concepts to mastery • If needed, allow calculator use for basic operations to allow focus on problem solving • BE PATIENT- Math can be a traumatic experience and is highly emotional because of past failures.
