What on earth is Dyscalculia?
The word Dyscalculia comes from Greek and Latin, which means, “counting badly.” It refers to a wide range of life-long learning disabilities involving maths. In 2013 The American Psychiatric Association defined Developmental Dyscalculia as a“ Specific learning disorder that is characterised by impairments in learning basic arithmetic facts, processing numerical magnitude and performing accurate and fluent calculations. These difficulties must be quantifiably below what is expected for an individual’s chronological age, and must not be caused by poor educational or daily activities or by intellectual impairments.”
Here is a short video that explains dyscalculia

How common is it?
Experts estimate that 4-6% of the population have this learning disability. This means that there is probably at least one child in every class struggling with math. And yet many teachers have never heard of Dyscalulia. As a result thousands of learners go through school without diagnosis. My son was one of them. Every one of his primary school teachers noted the specific struggles he had with math and organization. But NONE OF THEM had heard of dyscalculia, so they didn’t make the connection. My son wasn’t diagnosed until grade 9 and he was one of the lucky ones“As a child, I was called stupid and lazy. On the SAT I got 159 out of 800 in math. My parents had no idea that I had a learning disability.” Henry Winkler (actor and dyscalculic)
The sad thing is that diagnosis can make a huge difference. Once some learning accommodations had been put into place my son went from failing math to passing with flying colors. How I wish he could have been diagnosed when he first started school. It would have made a huge difference. Not only would it have saved us hours of frustration, but his struggles had severely impacted his self-esteem.
If you are a teacher
I would beg/plead that you learn all you can about this learning disability. Become familiar with the symptoms. It is very likely that at least one child in each of your classes will have this disability. A diagnosis could make a huge difference in their lives.If you are a parent
Find out all you can about Dyscalculia. Knowledge is power and it will help you become an effective advocate for your child.Signs of Dyscalculia in Kindergarten Students

- May have difficulty keeping up with rapidly changing physical directions in gym class.
- May have left/right confusion.
Signs of Dyscaculia in Grade School Students
- Has difficulty learning and recalling basic math facts, such as 2 + 4 = 6. Finds multiplication tables extremely hard.
- Still uses fingers to count instead of using more advanced strategies (like mental math).
- Struggles to identify math symbols such as +,-, x, ÷ and to use them correctly.
- Struggles to identify clue words with math operations, so finds math word problems very hard.
- Has trouble with place value, often putting numbers in the wrong column when doing calculations.
- Has trouble writing numbers clearly. When writing, reading and recalling numbers will show number additions, substitutions, transpositions, omissions, and reversals.
- Has trouble reading a clock and the understanding time.
- Avoids games that require math skills or keeping score.
- Weakness in visual and spatial orientation. Gets lost/ disoriented and looses things. May have left/right confusion.

Are you thinking about a particular student?
Are you thinking about a specific student and wondering if they have this learning disability? It is very possible that they do. If you have 20 children in your class, chances are that 1 of them will have Dyscalculia.Accommodations
There are lots of ways to help students diagnosed with Dyscalculia. As with all learning difficulties there is no one-size-fits-all approach. You will have to try different approaches. Here are a few ideas that really helped my son:- Permission to use the calculator for anything involving numbers
- Given extra time to do math, especially on exams
- Ensuring that all instructions are written, as those with Dyscalculia often have a hard time processing and/or remembering a list of verbal instructions
- Using graph paper to help keep the numbers lined up for calculations
- Permission to read math problems out loud if helpful
- Providing uncluttered worksheets, so that students are not overwhelmed with too much visual information
- When presenting new material, make sure students can write each step down and talk it through until they understand it well enough to teach it back
