That should be exactly what she knows and has learned in school.  Once you know the terminology, it is very simple.  Doubles are 4+4, 5+5, etc., which most children learn easily and before other math facts.  Counting on, or count plus one, is 4+1, 5+1, etc., which is simply counting one more number.  So a double plus one is another way of adding 4+5, by breaking it up into 4+4+1, which is easier for some children.   [/quote]

But why make kids memorize doubles?  Why fill their heads with unnecessary terms and strategies?  What exactly this whole "double" concept is for? It's useless for additions and useless for multiplication.  In multiplication are you going to say to your kids "Doubles times three?"

I came a very strong school of math.  And anything that wasn't the shortest, most elegant solution was not accepted in  my math classes.[/quote]

If your math skills were that strong, you would have no trouble understanding the value of learning these strategies, especially for kids who don't immediately comprehend it. Also, the "shortest, most elegant solution" is an appropriate approach once you understand the fundamentals (which is not the same thing as memorizing a bunch of facts and equations. The point of math right now isn't to get to the answer to 3+4 as quickly as possible, it's to understand why 3+4=7, and to understand multiple ways of thinking about the solution so that, when you get more advanced, you're more capable of arriving at the "shortest, most elegant solution."[/quote]
