Vision & Math
Visual processing
problems commonly affect math learning and achievement.
Some common visually-based problems in math learning
include:
"Careless" Mistakes
Careless mistakes
may result from missing visual details, skipping words
while reading word problems, or accidentally missing
numbers or problems. Children with unrecognized visual
problems often also have sloppy writing so that numbers
may not line up in the correct columns and errors in
calculation result.
Number & Symbol Reversals
Confusion with
similar letters and symbols - number reversals of '2'
and '5', mistakes with > and <, and other math
operations.
Errors of Math Quantity
Dyscalculia is
often seen in association with spatial difficulties.
Students with dyscalculia may have problems associating
numbers with quantities. This may mean being able to
count automatically (rote memory), but work hard to
remember which numbers are bigger or smaller than
others.
Struggles with Multi-stepped Math
Children with visual memory problems often struggle a
great deal with multi-stepped math problems. It's
because they may quickly forget spatial order (working
from right to left? or left to right?) and make mistakes
of sequence and place value.
Visual memory weakness also makes it harder to
automatically remember the spatial flow of steps in
problem solving. Long division can be very difficult for
students. Geometry can also be very challenging.
Problems with Graphs,
Diagrams
Children with visual perceptual problems may really
struggle with graphs and diagrams. Depending on the sort
of problem a child has, errors of omission,
part-to-whole or whole organization may lead to learning
errors. If visual memory is poor, graphs and diagrams
may need to translated into words or the language of
numbers and mathematical relationships.
