Title: A Different'iated Mathematics Classroom


1
A Different.iated Mathematics Classroom
  • February 7, 2007
  • Presented By Dr. Laura Rader

2
Agenda
  • Welcome and Opening Remarks
  • PART I PREPARE YOURSELF
  • Who are our struggling
  • learners? (activity)
  • Operational Definitions
  • Principles of a
  • Differentiated
  • Mathematics Classroom
  • BREAK (15 minutes)

3
Agenda Continued
  • PART II MATH, MAKING A
  • DIFFERENCE- YOUR STUDENTS CAN DO IT!
  • Taking the magic and mystery out of
    math

4
The river-crossing problem.
  • Nineteen campers are hiking through Acadia
    National Park when they come to a river. The
    river moves too rapidly for the campers to swim
    across it.

5
The campers have 1 canoe, which holds 3 people.
On each trip across the river, 1 of the 3 canoe
riders must be an adult. There is only 1 adult
among the 19 campers. How many trips across the
river are necessary to get all the children to
the other side?
6
Are any of these middle school students in your
mathematics classes?
  • Suzie gets the assignment wrong because sloppy
    writing led to misreading and misalignment of
    numbers
  • Jeff has not yet memorized the multiplication
    tables
  • Juan reverses numbers when copying from the book
    or the chalkboard
  • Ashley cannot decide what to do when solving
    math word problems
  • Alfredo cannot remember algebraic formulas
  • Gerard cannot remember the procedural sequence
    for division computation

7
Reality
  • The reality is that approximately 5-8 of
    school-age students have memory or other
    cognitive deficits that interfere with their
    ability to acquire, master, and apply
    mathematical concepts and skills (Geary, 2004).
    These students with mathematical learning
    disabilities (MLD) are at risk for failure in
    middle school mathematics because they generally
    are unprepared for the rigor of the middle school
    mathematics curriculum.

8
DyscalculiaSpecific Types
  • Verbal Dyscalculia (oral language)- a math
    disorder in retrieving mathematics labels, terms,
    and symbols
  • Practognostic Dyscalculia (Practo doing,
    gnostic knowing, i.e. knowing by doing) a math
    disorder in applying math concepts when using
    manipulative objects in the environment (either
    visual or three-dimensional)

9
DyscalculiaSpecific types Continued
  • Lexical dyscalculia (reading)- a math disorder
    that involves impaired reading of math vocabulary
    and symbols
  • Graphical Dyscalculia (writing) a math disorder
    that is an impairment in the writing of
    mathematics symbols, equations, and other
    relevant language terms

10
DyscalculiaSpecific Types Continued
  • Ideognostical Dyscalculia (ideas) a math
    disorder that centers on impaired mathematical
    thinking or impaired conceptualizations (the
    ideas) in mathematics
  • Operational Dyscalculia (operations) a math
    disorder focusing on impaired applications of
    algorithms to the four basic math operations

11
ACTIVITY
  • Please take 10 minutes to work through the
    problems with your colleagues.
  • Determine the error pattern
  • Determine the specific type/s of dyscalculia
  • Discussion to follow

12
Rationale for Differentiation
  • Instruction can be a one size fits all approach
  • Gives students an opportunity to express
    themselves
  • Gives students ownership for their learning

13
Differentiated Instruction
  • suggests that you can challenge all learners by
    providing materials and tasks at varied levels
    of difficulty, with varying degrees of
    scaffolding, through multiple instructional
    groups, and with time variations...

14
Differentiated Instruction
  • Further, differentiation suggests that teachers
    can craft lessons in ways that tap into multiple
    student interest to promote heightened learner
    interest.
  • Carol Ann Tomlinson

15
Characteristics
  • Teachers begin where the students are
  • Engages students through different learning
    modalities
  • Students compete against themselves
  • Teachers use classroom time flexibly
  • Teachers are diagnosticians, prescribing the best
    possible instruction for each student.

16
3 Key Questions
  • WHAT IS THE TEACHER DIFFERENTIATING?
  • HOW IS HE DIFFERENTIATING?
  • WHY IS HE DIFFERENTIATING?

17
Tomlinsons 8 Strategies
  • Compacting the curriculum
  • Independent study
  • Interest groups
  • Tiered assignments
  • Flexible grouping
  • Learning centers
  • Adjusting questions
  • Mentorships

18
Strategy 1
  • Compacting the curriculum

19
Green Contract
  • A- or higher.
  • May skip all odd problems from assignments.
  • May loop out of class lectures.
  • Choose a project
  • Green projects are more in depth.

20
Blue Contract
  • B or higher
  • May skip every third problem in assignments
  • May loop in and out of class lectures.
  • Choose a project

21
Results
  • Increase value of mathematics for students who
    chose to contract
  • Decreased motivation for the whole class
  • Increased motivation for individual students

22
Strategy 2
  • Independent study

23
Strategy 3
  • Interest groups-multiple intelligence survey

24
Strategy 4
  • Tiered assignments

25
Circle one
  • GREEN I know and can use the distributive
    property.
  • YELLOW I have heard of the distributive property
    before and vaguely remember it.
  •  
  • RED I do not know what the distributive property
    is or I do not understand it.
  •  
  • Solve 9 2(2x 2) 2

26
Green
  • Do 2 problems from each section in the assignment
    from the book AND choose 1 of the following
    projects
  • Research the history of the distributive
    property and give a report or presentation
  • Research the applications of the distributive
    property and demonstrate or give a report

27
Green
  • Be a student aid to others in the classroom
    (limit one aid per day)
  • Select a project from the end of the chapter in
    the book.
  • Propose another idea. Include your timeline.

28
Yellow
  • 1.a) Calculate mentally Using the distributive
    property how much do 5 tapes cost if they sell
    for 8.97 each?
  • b) Monicas hourly wage is 12.00. If she
    receives time and a half for overtime, what is
    her overtime- hourly wage?

29
Yellow
  • 2. Write five problems similar to the above
    examples that can be solved mentally using the
    distributive property. Exchange your five
    problems with another group and solve them.
    Compare your answers.
  • 3. Complete the assignment at the end of the
    lesson. You may work in groups if you desire.

30
Red
  • 1. Work with Mrs. Z.
  •  
  • 2. Do the first five problems of the assignment.
  • 3. Complete the assignment. Feel free to work
    with a neighbor.

31
Strategy 5
  • Flexible grouping

32
Strategy 6
  • Learning centers and assessment stations

33
Strategy 7
  • Adjusting questions/prompting a student with a
    question ahead of time (helps with verbal
    dyscalculia)

34
Strategy 8
  • Mentorships

35
Differentiated instruction has as many faces as
it has practitioners and as many outcomes as
there are learners. Kim Pettig
36
Part IIActivity
  • Why are students with MLD such poor mathematical
    problem solvers?
  • Take a moment to solve the following problem
  • Caroline owns a dog kennel. She usually has 15
    dogs to care for every week. Each dog eats about
    10 pounds of food per week. She pays 1.60 per
    pound for food. How much does Caroline pay to
    feed 15 dogs each week?

37
Example continued
  • Now, stop and make a list of the cognitive
    processes and metacognitive strategies you used
    to solve the problem.

38
Process Suggestions
  • Rereading the problem or parts of the problem
  • Identifying the important information
  • Asking yourself questions
  • Putting the problem in your own words
  • Visualize or draw a picture or diagram of the
    problem
  • Telling yourself what to do
  • Estimating the outcome
  • Working backward and forward
  • Checking that the process and the product are
    correct

39
How can we teach students with MLD to be better
math problem solvers?
  • Verbal Rehearsal- acronym RPV-HECC
  • R Read for understanding
  • P Paraphrase - in your own words
  • V Visualize draw a picture or diagram
  • H Hypothesize make a plan
  • E Estimate predict the answer
  • C Compute do the arithmetic
  • C Check make sure everything is right

40
Process Modeling
  • Thinking aloud while demonstrating an activity

41
Visualization- the basis for understanding the
problem
  • Students with MLD need to be taught how to select
    the important information in the problem and
    develop a schematic representation
  • Drawing a picture is not enough- students must be
    able to visualize the relationships among the
    pieces of information in the problem.

42
Role Reversal
  • Have students change places and become the
    teacher
  • Fosters students to become independent rather
    than dependent

43
Peer Coaching
  • Gives students opportunities to see how other
    students approach mathematical problems
    differently, how they use cognitive processes and
    self-regulation strategies differently and how
    they represent and solve problems differently.

44
Peer Coaching Example
  • Example Your parents want to buy new school
    clothes for you and they said you could spend
    150.00. Make a list of items you would buy.
    Use newspaper ads to find prices. Then,, decide
    which items you will actually purchase. Work
    with your group to complete your list. Compare
    your final purchases with the purchases of the
    other group members.

45
Performance Feedback
  • Immediate, corrective and positive
  • Allow students to graph their own progress

46
Distributed Practice
  • To maintain high performance students with MLD
    need to practice intermittently over time

47
POSSIBLE ASSESSMENT STRATEGIES
  • Portfolios
  • Two grades personal grade grade compared to
    class
  • Give superscripts A1, A2, or A3
  • Replacement grade

48
TIPS FOR SUCCESS
  • Clearly express criteria for success
  • For projects, stress planning and check-in dates.
  • Provide choice for your students
  • Use task cards or assignment sheets
  • Give students as much responsibility for their
    learning as possible

49
TIPS FOR SUCCESS
  • Begin with a familiar topic
  • Take small steps
  • Gather various resources
  • Clearly express criteria for success
  • Have a plan to help students when you are busy.

50
If you finish early
  • Choose another project
  • Do Math Stumpers
  • Explore math web sites
  • Try to solve Tangrams
  • Try to solve wooden puzzles
  • Play a 2 person game
  • Help your neighbor

51
Possible Positives
  • Teachers are partners with their students
  • Student interest is tapped
  • Greater retention
  • Choice is motivating
  • Allows students to learn at different paces

52
Possible Positives
  • Allows for multiple forms of intelligence
  • Gives teachers a different view of students
  • Challenges all students

53
FINAL THOUGHTS
  • In the end, all learners need your energy, your
    heart and your mind. They have that in common
    because they are young humans. How they need you
    however, differs. Unless we understand and
    respond to those differences, we fail many
    learners
