Hi I'm Kay and teach maths to primary age children. I have a special interest in children with maths learning difficulties and am currently looking into teaching and understanding children with dyscalculia:)
Hi Kay, I didn't know what that was, I had to look it up. Not to lessen the severity of those childrens suffering, I can say that math is really hard. I think we all have learning problems with it. At least I do. Math cost me a career in Biochemistry. For some reason I developed the integer disease. I thought that all problems had solutions like 1,2,3,4, 1/2, 1/3 and √2. The first time I saw scientific notation and decimals I freaked out. I couldn't grasp how some physical process could have an answer like 1.237653 of anything. Stymied me from that point on and I eventually grew to hate my favorite subject.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.
