First of all, math facts tend to be very difficult for students with dyslexia to memorize. The memorization of multiplication and division tables tends to be very challenging and requires tremendous amounts of repetition.
Even after they seem to have mastered these math facts, a student with dyslexia may still need refreshers from time to time. They may have days in which they really struggle with those facts again. You can find more information on dyslexia symptoms from various online sources.
Math facts are fundamental to being able to do the math, and for that reason, they are heavily emphasized in the early grades. Memorizing math facts helps students establish number sense, and they are also important to other concepts that come later.
Math is a building block subject, and it’s important to establish the fundamentals before moving on. Due to the challenges of memorizing math facts, multiplication and division tend to be difficult for kids with dyslexia. Multiplying and dividing numbers, and having a sense of how these concepts work, may be challenging.
Secondly, copying or organizing problems can be difficult for students with dyslexia. For example, if a teacher is reading a problem and asking students to write it down, a student with dyslexia may have a very difficult time writing it down accurately.
They may hear a number but copy it down on their paper differently, or they may have trouble lining the elements of the problem up. To correctly do math problems on paper, it is necessary to line up digits accurately.
