How high is a normal room?
It's not a trick question. Just estimate the height of a typical room. Okay? Now read on.
Students who struggle to learn mathematics may have a neurocognitive disorder that inhibits the acquisition of basic numerical and arithmetic concepts, according to a new paper. Specialised teaching for individuals with dyscalculia, the mathematical equivalent of dyslexia, should be made widely available in mainstream education, according to a review of current research published in the journal Science - Dyscalculia: From Brain to Education
But before you decide that this is what you have bear in mind that these are some of the common indicators of dyscalculia:
(i) carrying out simple number comparison and addition tasks by counting, often using fingers, well beyond the age when it is normal, and (ii) finding approximate estimation tasks difficult.
An example of i) is if in calculating which is the larger of two playing cards showing 5 and 8, you count all the symbols on each card. An example of ii) would be if you estimate the height of a normal room as two hundred feet.
