# The Square root rule

I’ve been doing a lot of research and reading about dyslexia and came across an absolutely amazing book that has just changed my whole understanding of dyslexia. Its called The Dyslexic Advantage: Unlocking the Hidden Potential of the Dyslexic Brain

There are some many insightful chapters about the nature of the dyslexic brain including one that explains how difficult it is for dyslexics to undertake procedural learning i.e. learning how to do something, and learning it to the point where it is automatic, so you know how to do it instinctively.

The authors, Brock Eide and Fernette Eide, have coined something that they refer to as the **square root rule **based on lots of research.

The rule essentially gives the following guide: it takes the square root longer to learn something if you are dyslexic than if you aren’t. So if its takes 10 hours for a person without learning difficulties to learn something, it would effectively take a dyslexic 100 hours to learn the same task. Sobering!

I practically shouted “Aha” loud. You see now I understand even more deeply why spelling patterns are a challenge, why times tables are a challenge and indeed why concepts come quickly to my daughter and then seem to disappear just as fast. Indeed, now I fully understand what is meant when they say **repetition** is the most critical of the learning strategies.

I understand also that my daughter is not pretending and also, that the concepts will eventually stick. We just need to keep at it.

# Times Tables Challenges

Retention of information is a challenge for my daughter. She picks up concepts really quickly, particularly maths concepts, but then forgets them in record time too!

So typically, this is what happens:

She learns a new concept, I celebrate the fact she took record time to understand the new idea, faster than her peers even (yay!), we do practice questions, she answers all the questions flawlessly – Job done. A week later I present her with a question from the topic and she stares blankly at the question and at me. “Have we done this topic Mummy”? she asks.

I’ve read and understood that retention is a challenge for dyslexics and that learning for them involves repetition, more repetition and even more repetition.

As we well know, this makes learning times tables a near on impossibility. We’ve tried everything – books, apps, practice sheets etc. She learns and she forgets.

Someone recommended singing timetables to me. So I searched amazon and there they were. The music is a bit cheesy and the voices a bit odd, but they seem to be working. We’ve learned 5’s and 3’s so far. I’m encouraged. Its super early days, but I’m hoping this will be the solution. We’ve got 10 more tables to go.

Wish me luck – I will keep you all posted.

Try them out, these are the ones I have.
