Dyslexia and math / maths
Many dyslexic children and teens aften experience
problems with math/s because of their difficulties with sequencing. Many have
not yet learned the basics - how to count to 100 forwards and backwards, and do
not understand any processes beyond addition. Jean Herold
describes some techniques which will help.
Many dyslexic children
and teens have problems in some ares of math/s, especially the multiplication
tables, fractions, decimals, percentages, ratio and statistics. A
dyslexic student usually needs extra instruction particularly as new concepts
are introduced. With
this subject, it is particularly important to grasp each concept thoroughly before
moving on. If not instructed properly in math/s, it will become yet another thing
to weigh down their self-esteem. Sequencing
and short-term memory Problems
in math/s can arise from a dyslexic child's difficulties with sequencing. Getting
numbers in the correct order, and being able to reverse that order is a challenge
for the student. A
problem with short-term memory can make it particularly hard for the student to
learn the multiplication tables. To
help a student with math/s the first thing that needs to be established is how
much they know or understand about the subject. It cannot be assumed because of
age or grade how much a student knows. Small
steps Teach
math/s concepts sequentially and in small steps. Do not move on to another concept
until the student is ready and thoroughly understands the preceding concept. For
example, do not move on to counting backwards until basic counting has been mastered.
The following exercises can be beneficial in reinforcing the relationship of numbers
to actual quantities. They utilize the same multi-sensory approach used
to teach dyslexic children to read. Introduce these methods as games, keeping
them a fun activity. If the student becomes tired, seems distracted or bored at
any point move on to another activity, or take a break for a while. Counting
to 100
Have
a child with dyslexia arrange 100 counters in a long line on the floor. Have her
place a marker after each ten. The child can then practice counting all the way
through to 100. Teach tens by using a different colored counter in place of the
tens number so that they easily stand out. After
that, they can learn to count by fives. The counting of numbers by ten and five
will help the child immensely when it comes to multiplication and time telling
skills. Have
the child count forwards until they can do so fluently, then they can start to
count backwards. Practicing counting can be done in any situation, counting cars
as they pass by, or stairs as they climb up them. Another
exercise that can be done anywhere - in the classroom by the teacher, or at home
with a parent - is to call out a number and have the child call out the following
one. At first the hardest numbers for the child to remember are usually where
there is a change of tens, as in 29 to 30. Multiplication
and division Multiplication
and division are the most difficult for a child with dyslexia to master. It will
make it easier for the child to learn if they actually understand the concept.
The following may help: collect 5 pairs of items, gloves, shoes, toy animals,
anything as long as the pairs are the same. Lay out the pairs in front of the
child, show her that there are two items in each pair, one pair has two items,
two pairs has four items, etc. When the child sees the five pairs have ten items,
explain as you write it down, that is what 5 x 10 means. This
exercise can be repeated with each of the different pairs until she understands
what the "2 times" means. Once the child is familiar with the 2 times table, they
should begin to work on all the tables in the following order: 2x, 10x, 11x, 5x,
3x, 4x, 9x, 6x, 7x, 8x, then finally 12x, which they should know from the other
tables.
When
first using worksheets, use pictures of familiar animals or items for students
to count. If a student has difficulty with one particular fact show them how to
use the facts they do remember to help them. An
example of this is if a student knows 6 x 5 well, show them how to use that to
figure out 7 x 5 by counting up by five. Relate
mathematical story problems to things they like and their friends or family, this
way they have the added dimension of visualization to work with. Games
work particularly well Games
work particularly well with dyslexic children as they seem to have an aversion
to plain work sheets. Children enjoy playing Bingo. This multiplication
Bingo game is a big hit with most kids. Make a Bingo type card on a piece of paper,
fill the squares with the answers to all the multiplication facts, up to 6 x 6
with regular dice, 9 x 9 and 12 x 12 (or with the polyhedral dice available at
school supply stores). Take it in turns to roll the dice; multiply the two numbers
rolled and mark it off on the players' Bingo sheets. Without
making it too obvious, let the child win any games to build up their self-confidence.
Teach the child
to talk through math/s problems, saying it softly to themselves, without
disturbing others. This will employ auditory as well as visual memory abilities.
Explain to them how this will help because the brain can store different kinds
of memories. Often a child will read a whole problem, remember some numbers and
do any kind of math calculation that comes to mind! Show the student how to jot
down the key facts and symbols in a problem as they come up. Use
a calculator
Show
a child with dyslexia how to use a calculator. Students should not use the instrument
to do all of their math/s work, but to check their calculations and make corrections
where necessary. Make
individual worksheets for students. Structure worksheets to meet the students
knowledge and ability; simplify word problems so they will not be an obstacle
for dyslexics; customized sheets will allow for success, not failure.
Real
coins When
teaching about money use real coins instead of plastic, this is far more fun and
exciting for the children. It is not always necessary to spend a fortune on items
for tactile use; change from your pocket, pieces of cereal, simple circles cut
out of colored paper are great for whole number and fraction work. Utilize
the many resources available to construct a suitable curriculum for students.
Websites like
www.dyslexia-teacher.com has many
great suggestions for instruction ideas. Many
computer games such as Treasure
Math Storm by Learning
Company are fun and provide an excellent means of math practice. Commencing
with basic multi-sensory instruction, sequential small steps, verbalization and
visualization techniques, and review and practice, there is no reason for any
child not to become a competent mathematician. !
