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 Copyright The Dyscovery Centre literally 2011

TEMPERATURE AND REGULATION
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.

ADHD Behaviour
Copyright The Dyscovery Centre 2011
Behaviour + Language Children with poor understanding have more behaviorual difficulties
Children with difficulty expressing themselvesmore socially withdrawn and anxious
The Dyscovery Centre Summary by the Centre Copyright for Integrated Healthcare Research, 2006 2011
Conduct + Language+ autistic features 2/3rds of children with conduct disorders had pragmatic language impairments Gilmour et al (2004)
Copyright The Dyscovery Centre 2011
ADHD + Asperger’s
21% of children with severe ADHD met criteria for Asperger’s syndrome 36% showed ‘autistic traits’
Copyright The Dyscovery Centre (Fitzgerald and Corvin, 2001) 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)

So THERE is spectrum of difficulties
Copyright The Dyscovery Centre 2011
What is DCD?
Copyright The Dyscovery Centre 2011
DCD Changing terminology – clumsy child syndrome – minimal brain dysfunction – developmental dyspraxia
Copyright The Dyscovery Centre 2011
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 Copyright The Dyscovery Centre 2011
Motor Impairment Motor difficulties as a primary defining condition e.g. • Cerebral palsy • Developmental Coordination Disorder
Copyright The Dyscovery Centre 2011
Motor Impairment Motor difficulties as a secondary defining characteristic: Learning difficulties - general/specific Sensory difficulties - sight/hearing/other Attention and Behaviour difficulties - e.g. ADHD Copyright The Dyscovery Centre 2011
A diagnosis of DCD does not imply a cause ‌ it is a collection of symptoms (similar to ADHD, Dyslexia etc.)
Copyright The Dyscovery Centre 2011
DCD DSM1V criteria Defining 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
Copyright The Dyscovery Centre 2011
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
Copyright The Dyscovery Centre 2011
Gender • Reported to be 3:1 • Internalisation v externalisation of symptoms • Parents concerns and perceptions may differ for boys and girls
Copyright The Dyscovery Centre 2011
Key features of DCD •Learning new tasks •Self care tasks •Writing – quality and speed •Riding a bike and balance tasks and dual tasking •Team games AND often has •Organisational difficulties •Low self esteem and difficulty sustaining friends •Mathematics Copyright The Dyscovery Centre 2011
But we can make assumptions out difficulties without checking out the reasons e.g. A child having difficulties writing down information from a whiteboard Copyright The Dyscovery Centre 2011

What is dyscalculia?
Copyright The Dyscovery Centre 2011
DSM1V 315.1 Mathematics Disorder As 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. Copyright The Dyscovery Centre 2011
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! Copyright The Dyscovery Centre 2011
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
Copyright The Dyscovery Centre 2011
Core primary mathematical competencies Numerosity Ability to accurately determine the quantity of sets up to 3 or 4 items, or events, without counting
Ordinality Implicit understanding of “more than” & “less than” for comparison of sets of 3 to 4 items
Counting Nonverbal system for enumerating small sets of items & implicit knowledge of counting principles (1 to 1 correspondence)
Simple arithmetic Sensitivity to increases (addition) and decreases (subtraction) in the quantity of small sets of items
Estimation Inexact estimation of relative quantity, magnitude, or size
Geometry manipulating shapes, visualising Geary (2007): Child Dev. 78(4) Copyright The Dyscovery Centre 2011
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
Copyright The Dyscovery Centre 2011
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
Copyright The Dyscovery Centre 2011
Assessment • Standardised Mathematical tests- WAND, or comparison to peers of similar age
Copyright The Dyscovery Centre 2011
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

Copyright The Dyscovery Centre 2011
Poor working memory In completing math problems, students with poor working memory will have difficulty with: Mental arithmetic • will tend to use ‘finger counting’, • need visual representation, or manipulatives Retrieval 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 Copyright The Dyscovery Centre 2011

Getting harder Harry 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? Copyright The Dyscovery Centre 2011
Breaking down the problem What 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….

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 Copyright The Dyscovery Centre 2011
