@Ian: Maybe at the tender age of 70 I'm getting a bit grumpy,..

Tell me it isn't so (LOL)

Since you "lernt calculus", do this one for me. Drill a 2 inch hole perpendicular to the axis of a 2 inch round rod. How much material is removed? Oh, and the kicker is... I'll do in in my head before you even get an approximate answer with your "numerical methods". ......... I'm finished, what answer did you get?

Knowing the correct tool to use, and how to use it, makes a lot of "problems" go completely away. Calculus is one of those tools, as are the multiplication tables.

I once worked with some guys who could in head multiply in hex..  

   But the code the wrote was terrible, VERY quaint, but impossoble for others to work on, 

    does that make them clever and others stupid ?

 

In the UK, we once upon a time had 12 pence in a pound, so may be a reason to learn up to 12 times table,

 

BUT, we used to have 14 pounds in a stone, so may be we shou;d have learnt up to 14 !

BUT , we used to have 16 oz in a pound, so may be we should all have learnt up to hex.

 

UNLESS that was a troy pound which has 12 oz,

 

But then again we had 20 oz in a pint , so may be tables up to 20.

 

Sorry , I'm the generation that was forced to learn tables up to 12 * 12, 

    what a waste of time,

 

What one learns tables to is an arbitury number, Id suggest binary is just fine !

    why should we force a number on to the new generation just "Because we did "

Heck, I learnt how to use log tables, and a slide rule, are we suggesting that thats a great skill to have.

 

Mind you, I lernt calculus, don't know how many times I have used that int he kast 40 years,   Essoecialy when I learnt that in the real world, the number of things that can be solved with calculus is small, numerical methods can and do sove them all,

    bu thats another story.

@Ian - and if you're an Australian over the age of 60, odds are you can spell and know what to do with an apostrophe.  Most of the younger ones don't....

Issac Asimov's "A Feeling of Power" takes place in a future where pocket calculators are so handy that people don't even bother to learn basic math skills anymore because the calculator does just fine. So when someone "reverse engineers" math so he can do it with a pencil and paper, it's a revelation.

Maybe at the tender age of 70 I'm getting a bit grumpy, but the dumbing down of the three R's is horrifying. Just look at the einternet to see the degradation in the quality of (non-handwritten) writing.

The over-reliance on results of calculators etc always being correct is also worrying. I remember there was once an experiment where a group of people were given calculators to solve a list of problems. What  the people didn't know was that there was a computer between the keyboards & screens of the calculators, & the computer randomly modified the results. Only a small proportion of the group noticed that the results were wrong.

A bit off this topic; I am annoyed by the misunderstanding betwwen resolution & accuracy. Advertisers seem to be the worst. An ad on the tv here in Oz from a superannuation business claims that "expected returns are better that 9.16%". Really! An example of using increased resolution for no purpose (perhaps it creates some sort of impression, but nothing to do with maths).

@David No, not a teacher, but I do work with educators.

 

I guess there's not as much need for cursive anymore, except for signatures, but even those are going digital. Sounds like your cursive writing may be part of the reason we've moved away from it. :)

@Jennray.... "This is supposed to encourage a deeper understanding of the connection between numbers..."

But if I'm in a supermarket and I want to buy three things for $7 I want to know instantly that it'll cost me $21.  And I do. What's more practical than that? As I said above, I don't know what I'd do without this knowledge, I use it all the time.  And if I have to multiply 30 000 by 700 I can straight away come up with 21 000 000 by a similar process.

> "I'm not totally convinced."  I take it then that you're not a teacher?  

BTW...cursive...I think it's called that because if you try to read mine, you curse.... :-)
