CMA Math - Discussion

Thanks abacus trainer for the elaboration.:)


i read somewhere that learning abacus is already training both left and right brain (regrdless of 2 hands method, etc). so not sure if that applies to 3G as well.

recently, i read an article, and it mentioned something about learning soroban abacus. it says that people who learn abacus does not know numbers. because whatever numbers the person see, he immediately use (mentally or not) abacus to calculate out the answer. simply out, he is the caculator.

Really? This is something new… Must research more on this…


@ abacus trainer. . So when or rather at which grade should the kid stop lesson?

[smurf]

such example of why people who learn abacus does not know numbers:

3G uses both hands too. It’s true regardless the type of abacus. Once you do mental sums, you are using both left and right brain. The human brain is quite complex, using it to control hands movement, left right hand coordination and performing mental sums, it’s probably all under a different department in the brain.


As for the article… A bit too "cheeem" for me. To me, it doesn’t mean that the Japanese man doesn’t know numbers. He just loses out on logic which he didn’t know. I don’t how many of us who has never learn abacus knows this logic.

Extract from the article…
"The number was 1729.03. I happened to know that a cubic foot contains 1728 cubic inches, so the answer is a tiny bit more than 12. The excess, 1.03 is only one part in nearly 2000, and I had learned in calculus that for small fractions, the cube root’s excess is one-third of the number’s excess. So all I had to do is find the fraction 1/1728, and multiply by 4 (divide by 3 and multiply by 12). "

When we are young, we learn to count. But as we grow up, we don’t count anymore. We add up the numbers using logic and by memory or experience (sum that we have done before numerous times in school). We already know the answers, 1+1=2, 7+3=10, 5+5=10. Our children are still at the growing phase and need to learn counting either through abacus or counting fingers.

Just my views… Sorry, I will stop replying from here.
