Myths about LD People with LD have lower intelligence.(33% are gifted.) They are lazy or stubborn. Children with LD can be cured or will outgrow it. Boys are more likely to be affected.(Girls are equally affected.) Dyslexia and learning disability are the same thing. Students with LD and ADHD cannot succeed in higher education. Joan A. Cotter, Ph.D., 2015

Characteristics of LDChild usually: Is more creative. Cannot learn by rote. Must understand and make sense of a concept inorder to remember it. Is more visual and hands-on. Dislikes worksheets. Finds it very difficult to unlearn. Joan A. Cotter, Ph.D., 2015

Problems Occurring with MathDyscalculia Reversals in writing numbers Poor number sense Slow fact retrieval Errors in computation Difficulty in solving word problemsDyscalculia mainly affects arithmetic, not otherbranches of math. Joan A. Cotter, Ph.D., 2015

How Math is Traditionally Taught Counting Learn sequence (number names by heart) One-to-one correspondence (one count per object) Cardinality principle (last number tells how many) Memorizing facts Flash cards and timed tests Rhymes and songs Memorizing algorithms (procedures) Using key words to solve story problems Joan A. Cotter, Ph.D., 2015

Traditional CountingFrom a child’s perspectiveBecause we’re so familiar with 1, 2, 3,we’ll use letters of the alphabet.A 1B 2C 3D 4E 5, and so forth Joan A. Cotter, Ph.D., 2015

Traditional CountingFrom a child’s perspectiveTry skip counting by B’s to T:B, D, . . . , T.What is D E? Joan A. Cotter, Ph.D., 2015

Compared to ReadingJust as reciting the alphabet doesn’t teachreading, counting doesn’t teach arithmetic. Joan A. Cotter, Ph.D., 2015

Counting-Based Arithmetic Rote counting to 100 in kindergarten. Calendars misused to teach counting. Counting on for addition. (Jack and Jill) Counting back for subtraction. Number lines are abstract counting. Skip counting for multiplication facts. Does not work well for money or fractions orreading graphs. Joan A. Cotter, Ph.D., 2015

Memorizing MathPercentage RecallImmediately After 1 day After 4 weeksRote32238Concept696958Math needs to be taught so 95% isunderstood and only 5% memorized.–Richard Skemp Joan A. Cotter, Ph.D., 2015

Memorizing MathAccording to a study with college students,it took them: 93 minutes to learn 200 nonsense syllables. 24 minutes to learn 200 words of text. 10 minutes to learn 200 words of poetry. Joan A. Cotter, Ph.D., 2015

Flash Cards and Timed Tests Often used to teach rote. Liked only by those who don’t need them. Give the false impression that math does notrequire thinking. Often produce stress – children under stress stoplearning. Not concrete – use abstract symbols. Cause stress (may become physically ill). Result in short-term learning. May lead to math anxiety. Joan A. Cotter, Ph.D., 2015

Joan A. Cotter, Ph.D., 2015

Visualizing Visual is related to seeing. Visualize is to form a mental image. Joan A. Cotter, Ph.D., 2015

VisualizingVisualizing is also needed in other fields: Reading Architecture Sports Astronomy Arts Archeology Geography Chemistry Engineering Physics Construction Surgery Biology History Joan A. Cotter, Ph.D., 2015

Grouping in FivesSubitizing Instant recognition of quantity is calledsubitizing. Grouping in fives extends subitizing beyondfive. Joan A. Cotter, Ph.D., 2015

Subitizing Five-month-old infants can subitize to 1–3. Three-year-olds can subitize to 1–5. Four-year-olds can subitize 1–10 by groupingwith five. Joan A. Cotter, Ph.D., 2015

GamesGamesMathBooks Reading Games provide interesting repetition neededfor automatic responses in a social setting. Games provide an application for newinformation. Games provide instant feedback. Joan A. Cotter, Ph.D., 2015

Place ValueThe problem English-speaking children often think of 14as 14 ones, not 10 and 4 ones. The pattern that is needed to make sense oftens and ones is hidden! Joan A. Cotter, Ph.D., 2015

Place ValueIts importance Place value is the foundation of modernarithmetic. It is critical for understanding algorithms. It must be taught, not left for discovery. Children need the big picture, not tinysnapshots. Joan A. Cotter, Ph.D., 2015

Math Way of Number Naming Only 11 words are needed to count to 100 themath way, 28 in English. (All Indo-Europeanlanguages are non-standard in number naming.) Asian children learn mathematics usingtransparent number naming. Mathematics is the science of patterns. Numbernames need to be an example. Children who are hearing-impaired can distinguishbetween 14 and 40, and 13 and 30. Learning two languages helps brain development. Joan A. Cotter, Ph.D., 2015

Learning the FactsLimited success, especially for strugglingchildren, when learning is: Based on counting: whether dots, fingers,number lines, or counting words. Based on rote memory: whether flash cards,timed tests, or computer games. Based on skip counting: whether fingers orsongs.A child is considered to know a fact if they cangive it in 2–3 seconds.

Short Division Means we don’t write the stuff underneath. Should always be used for single-digit divisors. Is easier to understand than long division. Needs to be taught before long division. Is much more useful in real life. Is much quicker to perform for tests. Joan A. Cotter, Ph.D., 2015

Long Division Children with learning disabilities should not beexpected to learn long division. It can take monthsto learn it — an unwise use of time. It is a mostly memorizing a number of steps withlittle understanding. It is not a skill needed in advanced math. Dividingpolynomials does not entail guessing a trial divisor. Rarely performed on the job or in everyday life.What is important is estimating an answer andknowing what to do with any remainders. Joan A. Cotter, Ph.D., 2015

Compared to Reading Just as reading is much more than decoding,phonics, and word attack skills, mathematicsis much more memorizing facts and learningalgorithms. Just as the goal of learning to read is readingto learn and enjoyment, the goal of math issolving problems and experiencing wonder. Joan A. Cotter, Ph.D., 2015
