| This really surprised me. You'd think that with all the mathematics lessons they get that most of them would know this. Today I was teaching them numbers and symbols and only a few studens knew what square root meant - and not the English name, the symbol and mathematical meaning. I see some pretty complex geometry and algebra in their math workbooks - wouldn't they know this by age 13-14? |

Do you have any idea how many people think that 2X10^6 is double 2X10^3? Or how many people on here (or back home) can't even do simple "fraction to percentage" calculations. I know this site is mostly artsies, but I'm still appalled by some of the math done on here. And back home to be honest Still, I'm surprised these Korean kids can't because that is a test question and that's one of the few things they do right  |

A colleague of mine here in Saudi Arabia yesterday asked me how to average the scores for 6 grades. Not a weighted average- a simple average.
You have to have an MA to teach here. |

And I thought you were talking about the sliced vegetables found in Gimbaps...
...Sorry, I don't know my square roots, either, and was laughed at only the other day in my workplace. A few moments later, my co-workers asked me to translate a block of Hangeul into English, so I joked that knowing square roots clearly doesn't get them far in their jobs! |

I know - and here I was harbouring the delusion that they must at least be good at *something*. |

Did you rewrite it to:
144 ^ 1/2 = 12 |

I tried showing them the example of
___
/100 = 10 and some of them seemed to understand. But some others were quick to stress they hadn't learned that yet. Like with English skills it seems remarkable what some of them do and don't know. |

| I've never taught square roots in my English conversation classes. I didn't know anyone did. |

I was doing a lesson on numbers and thought I'd include symbols like +, -, %, =, etc. I guess that considering % and + are the only ones I've ever heard on government listening tests the rest may have been a bit superfluous for their level. |
