"Luke has 22 marbles.  He loses 18.  How many marbles does he have left?" 

 

No, don't think "subtract"; see it as calculating a difference.  Or, so say the educators of this new theory being tested with second graders.  Don't think "subtract"; think "difference"?  

 

But that's what subtracting is --- finding a difference.  Every school child knows that.  "I need a difference; I subtract." 

 

And how do you stop anyone from thinking what he is thinking.  The minute someone tells you not to think about a certain thing, that thing is exactly what you will think about.  I'll bet most of you remember the story of the person who was going to get a great gift if he managed not to think about it for so many minutes.

 

Whatever works.

 

Edit:  Spell-check played with the title.  The method is ACE-arithmEcole.  Now, let's see if this stays.

Those educators at Université de Genève have lost more marbles than they ever had.
