Our interpretation of each of these labels may be

differentCopyright The Dyscovery Centre 2011

We try to sort the symptoms and signs into boxes and label them up so they can be better understood


What’s your style? (trait)• Make some spelling errors, need to re-read

words on the page, take longer than others to retain information

• Slower learning a new skill, difficulty with right and left, a bit clumsy, took longer than others to learn to drive

• Find it hard to sit still, prefer to flit from one thing to another, see the big picture but not so good at the detail

• Prefer detail, not so good at the big picture, uncomfortable in large social groups, don’t always get the jokes, take things literallyCopyright The Dyscovery Centre

Right and left brains are connected by Corpus Callosum

•Language processing, once believed to be left- hemisphere-only, is now understood to take place in both hemispheres

•The left side processes grammar and pronunciation while the right processes intonation.

•The right hemisphere seems to deal with a general sense of space, while the left hemisphere deals with objects in specific locations.

Behaviour

ADHD

DCD


Behaviour + LanguageChildren with poor understanding have more

behaviorual difficulties

Children with difficulty expressing themselves-more socially withdrawn and anxious

Summary by the Centre for Integrated Healthcare Research, 2006Copyright The Dyscovery Centre 2011

Conduct + Language+ autistic features

2/3rds of children with conduct disorders had pragmatic language impairments

Gilmour et al (2004)


ADHD + Asperger’s

21% of children with severe ADHD met criteria for Asperger’s syndrome

36% showed ‘autistic traits’

(Fitzgerald and Corvin, 2001)Copyright The Dyscovery Centre 2011

Asperger’s + ADHD

More than 50% of adolescents with Asperger’s showed moderate to severe symptoms of inattention and hyperactivity

(Lecavalier ,2006,Fombonne et al ,2001)


Language + movement

So THERE is spectrum of difficulties


What is DCD?


DCD

Changing terminology– clumsy child syndrome– minimal brain dysfunction– developmental dyspraxia


Motor Impairments

A number of children have difficulties They can be placed in 2 main categories:

– motor difficulties as a primary defining condition

– motor difficulties as a secondary defining condition


Motor ImpairmentMotor difficulties as a primary defining condition

e.g.

• Cerebral palsy

• Developmental Coordination Disorder


Motor Impairment

Motor difficulties as a secondary defining characteristic:

Learning difficulties - general/specificSensory difficulties - sight/hearing/otherAttention and Behaviour difficulties - e.g.

ADHD


A diagnosis of DCD does not imply a cause

… it is a collection of symptoms (similar to ADHD, Dyslexia etc.)


DCD DSM1V criteriaDefining characteristics:

– A MOTOR IMPAIRMENT- Performance in daily activities that require motor co-ordination is substantially below that expected given the persons chronological age and measured intelligence

– measured with a normative test e.g. M-ABC, BOT ( however only 80% agreement between tests- different tests identify

different children

– B-IMPACTING on • Daily living• Academic achievement

– C and D Exclusionary clauses- intelligence, CP and other pervasive disorders

– And not due to a general medical condition– If mental retardation is present the motor difficulties are in excess of

those usually associated with it


DCD• Incidence - about 6%

• Depends on why are you looking… needs or resource led

• Depends on test you use• Depends on cut off to define the test


Gender

• Reported to be 3:1• Internalisation v externalisation of

symptoms• Parents concerns and perceptions may

differ for boys and girls


Key features of DCD

•Learning new tasks•Self care tasks•Writing – quality and speed•Riding a bike and balance tasks and dual tasking•Team gamesAND often has•Organisational difficulties•Low self esteem and difficulty sustaining friends•Mathematics


But we can make assumptions out difficulties without checking out the

reasonse.g.

A child having difficulties writing down information from a

whiteboardCopyright The Dyscovery Centre

Pain in a hand

Is the chair too low

Is there too much noise to hear what to copy

Too much to remember


What is dyscalculia?


DSM1V315.1 Mathematics DisorderAs measured by a standardized test that is given individually, the patient's mathematical ability is substantially less than you would expect considering age, intelligence and education. This deficiency materially impedes academic achievement or daily living. If there is also a sensory defect, the mathematics deficiency is worse than you would expect with it.


Symptoms and signs• Difficulty learning times tables• Difficulty with geometrical concepts• Difficulty with the “ language ” of

mathematics• Poor time concepts• Poor long term memory (retention &

retrieval) of concept mastery- may be able to perform math operations one day, but draw a blank the next!


Results in

• Poor management of money• Errors doing simple calculations• Difficulty understanding a series of

commands- 2 to the left/1 to the right• Difficulty keeping score in a game• Harder to play strategic games like chess


Core primary mathematical competencies

NumerosityAbility to accurately determine the quantity of sets up to 3 or 4 items, or events, without counting

OrdinalityImplicit understanding of “more than” & “less than” for comparison ofsets of 3 to 4 items

CountingNonverbal system for enumerating small sets of items & implicitknowledge of counting principles (1 to 1 correspondence)

Simple arithmeticSensitivity to increases (addition) and decreases (subtraction) in the quantity ofsmall sets of items

EstimationInexact estimation of relative quantity, magnitude, or size

Geometrymanipulating shapes, visualising

Difficulties can impact on different lessons

Science- weights, measures, recording, using tools

Sport- sequences of instructions, direction, timing, understanding the plan/teams

Geography- map reading, recording, orientation, graphs

History- time lines

CDT- measuring, tool usage, planning, language

Why do children with DCD have mathematics problems?

• Co-existence- DCD + dyscalculia• Consequence- DCD leading to

mathematics difficulties• Common underlying deficits• Co-existence of other developmental

disorders such as SLI


Assessment• Standardised Mathematical tests- WAND,

or comparison to peers of similar age


What are underlying cognitive skills needed for mathematics?

• Visual memory- perception, sequencing• Auditory memory• Language skills-receptive• Motor skills to use tools such as

rulers/protractors• Planning skills- EF


Why may these overlap?

What is auditory memory?


Auditory memory

• Remembering a series of instructions• A “small floppy disk”• Difficulty discriminating sounds and coping

with background noise

Signs of visual difficulties• Copying from the board• Needing to reread text• Avoiding reading out in class• Moving in a moving environment• Poor writing – spacing , not on the lines• Words bouncing• Spelling errors- longer words• Not getting their “abc ”• Geometry• Not being able to select key words and sense easily and

quickly

Planning and executive functioning difficulties


Presents with

• Difficulties working through a problem• Planning work• Prioritising• Selecting key information from a body of

words


Attention DIFFICULTIES


Slow processing

Inattention, as rated by classroom teachers, is a significant of Gr. 1 & Gr. 3 children’s in three key areas

• Fact fluency• Computation• Story problems


Poor working memoryIn completing math problems, students with poor working

memory will have difficulty with:Mental arithmetic• will tend to use ‘finger counting’, • need visual representation, or manipulativesRetrieval of math facts in word problems will tend to use• immature strategies (‘count all’, ‘count on from largest”)

Arithmetic procedures, such as ‘carrying’ &‘borrowing’

Ignoring irrelevant information in word problems


The linguistic difficulties (Tannock)

How do you help


Check the language of mathematics

+, add, and, plus, in addition, more

-, take away, minus, less, subtract

Highlight key words in a maths questionProvide a glossary or checklist


The understanding of maths

Joan has 12 sweets. She has twice as manysweets as Leela. how many has Joan got?

?


Getting harderHarry Potter has asked his friend Hermione for a potion to turn them and their friend Ron into birds. (The flying car is in for repairs, so they need to make the trip to Diagon Alley as birds.) Diagon Alley is 9 miles away and a dose of Hermione's potion lasts 50 minutes. They only have enough potion for one dose each. If they can go 24 miles an hour as birds, and they start at 4:30 p.m., can they get to Diagon Alley and back to Hogwarts again before the potion runs out at 5:20 p.m.? If so, how much time will they be able to spend in the Alley?


Breaking down the problemWhat exactly is the question you need to answer?• What do you need to know- what can you ignore• Can you draw a picture or rewrite the question in your

own words• Is there a formula you need to answer this- have you the

skills to do this• Have you checked your results• Have you been given enough time• Have you got the answer write but written it down wrong• Are you anxious….


Too many words

Don’t understand the words

Too little time

Can’t show workings

Work very untidy

Not sure of the process- where to start

Not sure what calculation to do

Know the calculation but make an error

Misread it

Need to reread it several times before starting


45 minutes

5 minutes


If planning is an issue• Check the student understands the

expected outcome• Providing worked model answers with the

processes as examples • Provide steps to complete- a scaffold• Talk through what is required by the

student- what skills are needed, how will points be apportioned in a test

• Provide a glossary of terms to refer toCopyright The Dyscovery Centre

Conclusions

• There are different reasons for someone finding mathematics difficult

• It is necessary to “ tease” out the reasons to find the right approach to help

• This often overlaps with DCD• Sometimes the child needs confidence to

become competent
