
Dyscalculia = “difficulty in learning or
comprehending mathematics” dyscalculia.org
•Identified in patients suffering brain trauma
resulting in math problems
•Arithmetic difficulties in calculation and number
memory deficits
“dys” = Greek, “badly”
“calculia” = Latin, “calculare”, “to count”

Are they related?


Confusing signs, +, -, x, ÷
Inability to tell which is larger
Rely on ‘counting on’ strategies
Difficulty with mental math, tables
Inability to remember concepts, rules,
sequences, formulas
Rotate numbers, 56 as 65
Difficulty estimating everyday time, money,
comparisons in amount and measurement
Difficulty with score keeping, rhythmsequential processing; dance, cheerleading

How does it feel to many children in math
class!
Errors often occur when students don’t know basic facts fluently

Sometimes charts are
used to assist poor

Two delivery trucks start from Central
City and Pottsdam City, which are thirtynine miles apart, making deliveries
along Route 7. The first truck leaving
Central City makes 7 stops and the truck
leaving Pottsdam City make 9 stops.
When the trucks meet the truck from
Pottsdam has traveled 11 miles farther
than the truck from Central City. How far
from Central City do the trucks meet?
How far from Central City do the two
