It concentrates on issues that are particularly important for less-advanced learners and for those who might be having special difficulties in learning mathematics. A major goal of the article is to develop a framework for understanding what effective mathematics teaching and learning is, because doing so is so important for struggling students and for research about them. Piaget's research had a fundamental influence on the on-going tension between understanding and fluency in the classroom, supporting efforts toward increasing understanding. But in some co...

Like the old MIT-Harvard rivalry, there's often a cortical battle for resources between spatial and verbal / visual "picture" thinking. In studies of spatial experts, high levels of spatial expertise were correlated with lower levels of verbal fluency, auditory verbal memory, and visual memory (for more, read here. But these studies, if you look at mathematicians and physicists talking about their thought processes (see Hadamard's Psychology of invention. From the mathematician Hadamard: "I insist that words are totally absent from mind when I really think...even after reading or hearing a questio...

Mathematical Disabilities:  An Underestimated Topic?  Journal of Psychoeducational Assessment 27, 171-174According to the special issue editors, and well understood by most people, is the fact that math literacy is becoming increasing important in our technological and information-based society.

The games are specially formulated to help children who find learning difficult including children with dyslexia, dyscalculia, ADHD and Learning difficulties.  However, they are based on normal child development and so can be used by anyone learning to read or learning maths.  I use them clinically in my practice and I have had great feedback from children of different abilities who have played the games.   I believe that using games to help children learn holds great promise for the future.  So try the games for free here and let me know what you think.

Having a spatial sense of number quantity is something that takes time to develop. Young children memorize number meanings (prefrontal), but having a sense of number quantity and inter-relatedness only develops as the parietal cortex matures. fMRIs of children with developmental dyscalculia (often seen with dyslexia)confirm the absence of a distance effect (the farther apart numbers, the quicker the ability to judge that one number is larger) compared to typically-developing children. So a critical feature of developmental dyscalculia is a failure to have a spatial or distance sense of numbers. Having this 'feel' for numbers helps one perform mental math quickly; if lacking, calculations must be performed in a mor...

Excerpt: "...after Phil and Susan Schwarz received a diagnosis for their son, Jeremy, of high functioning autism, they began to think carefully about their own behaviors and histories.Mr. Schwarz, a software developer in Framingham, Mass., found in his son’s diagnosis a new language to understand his own life. His sensitivities when growing up to loud noises and bright light, his own diffidence through school, his parents’ and grandparents’ special intellectual skills — all echoed through his and Jeremy’s behavior, like some ancient rhythm.His son’s diagnosis, Mr. Schwarz said, “provided a frame in which a whole bunch of seemingly unrelated aspec...

Whether we read or listen to words that have strong images, the intraparietal sulcus or IPS seems to be an important brain area to be activated. Images, like the IPS, are very multimodal, incorporating visual pictures, sound, sense of space, and movement. The graphs below show that whether strong image-evoking words were read or heard, the left IPS became quite active. The intraparietal sulci (right and left) are very cross-modal and interestingly implicated in some of the dyslexia-plus traits such as dyspraxia / motor planning difficulties, dyscalculia / impaired number sense, and verbal short term memory. Because in crossmodal areas, different senses and mot...

Our understanding of the biological basis of developmental dyscalculias greatly lags the dyslexias, but this latest review by Dehaene and his colleagues is a step in the right direction. The figure below shows three candidate locations for different subtypes of dyscalculia. I can add a little personal knowledge to this discussion too, because I have a deficits in both "number sense" and "multiplication facts" retrieval. My visual perception of number is absolutely fine, however.A math disability can be absolutely mind-boggling to a person doesn't have one.
