    I was using "Common Core math" as a term for the BS illustrated in the original post.

    Re: Common Core Math in U.S.A. Schools

    I was wondering how this new common core math compares to how math is done worldwide. Khonrai, could you say your method of teaching this is similar to how Thai students are usually taught?

    Hi

    it is not a new thing All of the math books I was given to teach from here in thailand use this method.
    can not say exactly how Thai teachers teach basic math but I assume similiar.

    I don't work it out, I just look at it and the answer appears in my head quicker than I can work it out.

    You were probably taught the same way I was -round up, do a simple subtraction and add back the amount rounded up by-a method so simple it becomes automatic. When I was at school we had a mental arithmetic test every Friday morning. There were no calculators in those days (yes, the abacus had been invented-it wasn't that long ago!! -but we never saw one, let alone taught how to use one!)
    When i was still working there was some basic maths to do-I used to stun people by providing the answers while everyone else was still accessing the calculator app on their mobile phones.

    Re: Common Core Math in U.S.A. Schools

    If I understand you correctly, Khun Don, that's the way I do simple math in my head.

    The way I was taught in school was to "borrow and carry", which I could never explain.

    Incidentally, I don't believe I have ever used any math beyond what I learned in elementary school, at least not intentionally. The basics have served me well both domestically and in my business.

    Yes-"borrow and carry"-I doubt if that is taught anymore in the age of calculators. Like you I have never had the need to use geometry etc.

    Re: Common Core Math in U.S.A. Schools

    Yes, if I work out the example above I would do 568 minus 300 is 268 and then add back the borrowed 7 giving 275. But I just have to look at it and 'know' the answer is 275.

    Like you I have never had the need to use geometry etc.
    If you ever need to estimate such things as tile, paint, wallpaper, or carpet, geometry comes in handy.

    I'd love to see Common Core's take on that discipline ...

    Re: Common Core Math in U.S.A. Schools

    I read in another forum where UK mentors teaching in Thailand were saying that Thai students were better in Mathematics compared to UK comparable students. But there were no details on how that subject is taught in both countries.

    As for me, all my life I have been trying to avoid Math like a plague. How I managed to finish school was the biggest miracle that ever happened to me!
