Dyscalculia may affect 3–8% of school-age children. So why is it so often overlooked? New CRPE research examines what schools and states can do to better identify and support students. crpe.org/the-missing-... #MathEducation #SpecialEducation

I think the maths historians would probably call this a 'surveyors' problem. Am in the process of making a sheet of them ... unless anyone already has such a thing. (The 40 and the 72 are the areas of the rectangles formed by the respective diagonals). #UKMathsChat #iTeachMath
