Title: Mathematics for Students with Learning Disabilities


1
Mathematics for Students with Learning
Disabilities
  • Background Information
  • Number Experiences
  • Quantifying the World
  • Math Anxiety and Myths about math
  • The Concepts (How they are formed)
  • Connected Teaching

2
Background Information
  • For every ___ years of schools, students with
    disabilities gain 1 year of math achievement.
  • What grade level of math do most high school
    students with learning disabilities top out at?
  • Most students with disabilities are not
    knowledgeable of needed consumer math skills
    (Algozzine et al., 1987).
  • Students with learning disabilities learn
    arithmetic through hills and valleys (Cawley,
    Parmar, Miller, 1997).
  • Many elementary school preservice teachers show a
    distaste for mathematics.

3
Overall concerns for students with learning
disabilities
  • Abstractness of numbers
  • Low number sense
  • Poorly formed ideas and algorithms
  • (requiring systematic instruction over
    constructivism)
  • Overgeneralization or incorrect use of algorithms
  • Poor recall of facts and procedures
  • Generalization and maintenance
  • (increases with difficulty of problems)
  • different presentation confuses

4
Number Experiences
  • A concept is an idea or mental image. Children
    develop concepts from physical objects through
    mental abstractions.
  • How can we help young children experience the
    importance of numbers?
  • Arithmetic is used to refer to manipulations with
    numbers and computations while mathematics is
    concerned with thinking about quantities and
    relationships among them (Polloway Patton,
    1993). To learn mathematics children must be
    taught the relationships between quantities and
    shown relevance behind arithmetic.

5
Number SenseAs important to math as phonological
awareness is to reading (Gersten and Chard, 1999).
  • Numerals to objects
  • Which is larger? 8 or 18
  • Which is closer to ___?
  • Counting
  • Counting on
  • Backwards on
  • Place Value
  • Writing numerals to match oral word and writing
    number words to match numeral
  • Note Use frames to teach number patterns
  • 2 4 6 8 12 14 16 20

6
Anxiety and Myths about math
  • Most elementary school children have positive
    experiences with mathematics and arithmetic.
  • Do adults have positive experiences with math?
  • Females score on average with males in math until
    secondary school (Xin, 2000). When males and
    females take the same math course in 11th grade
    they share a positive attitude about math in the
    12th grade. However, why do more men take
    advanced high school courses and score high in
    math achievement tests by the 12th grade?

7
The Concepts (How they are formed)
  • Sensorimotor- objects exist out of sight (0-2)
  • Preoperational- ability to think in symbols (2-7)
  • Concrete- manipulatives offer medium for
    instruction(7-11) conservation of objects
  • Formal operations- abstract problem solving (11)
  • Much research challenges Piagets theory
  • The order of development and the age of onset may
    be incorrect (Demby Miller)

8
Connected Teaching
  • CRA instruction
  • Fluency
  • Direct Instruction
  • Applications
  • Use of strategies
  • Best Practices
  • Advance Organizer
  • Model
  • Guided Practice
  • Independent Practice
  • Feedback
  • Maintenance and Generalization

9
CRA instruction
  • 62 of primary teachers use manipulatives while
    only 8 of secondary teachers use hands-on
    materials (Howard, Perry, Lindsay, 1996). Why?
  • Concrete - from fingers to objects
  • Representational - from objects to pictures
  • Abstract - from pictures to numerals
  • What programs cover some of these components?
    Touch math, etc.

Implement CRA instruction in your classroom.
Heres how
  • Choose the math topic to be taught
  • Review abstract steps to solve the problem
  • Adjust the steps to eliminate notation or
    calculation tricks
  • Match the abstract steps with an appropriate
    concrete manipulative
  • Arrange concrete and representational lessons
  • Teach each concrete, representational, and
    abstract lesson to student mastery (accuracy
    without hesitation)
  • Help students generalize learning through word
    problems and problem solving events

13
Algorithms and Fluency
  • Students apply algorithms properly after they
    learn the concept.
  • Why do shortcuts and algorithms not work as well
    when learning is new or the concept is difficult?
  • Fluency measures can only be used with
    instruction after students show mastery.
  • Fluency programs
  • Great Leaps Math
  • Precision Teaching
  • Teacher Made probes

14
Direct Instruction
  • Explain how you can apply direct instruction to
    teaching the 6 times multiplication table.
  • What other mathematics areas would be appropriate
    for direct instruction?

15
Word Problems
  • Students with disabilities do not paraphrase or
    visualize word problems. There is a connection
    between reading comprehension difficulties and
    poor performance solving for word problems.
    (Montague, Bos, Doucette, 1991)
  • How can we help? Examples
  • 7 cars 6 groups of
  • - 3 cars x 3 apples
  • ___ cars ___ apples
  • after seeing this pattern, leave some blanks for
    students to fill in. Then list needed information
    to solve, followed by extraneous info. Once
    students show mastery, have them write their own
    word problems.

16
Word Problems (cont)
  • Teach word problems as problem solving situations
    that need to be interpreted
  • Teach strategies for recognizing types of
    problems
  • i.e., focus on reading comprehension strategies
  • KWL
  • RAPQ
  • Word walls for vocabulary

17
Sum it Up
  • What activities can we do in the classroom to
    help children prepare to think in symbols and
    numbers?
  • What is the difference between elementary or
    middle school boys and girls?
  • What is CRA instruction?
  • When should a teacher use fluency or algorithms
    to solve math problems?
