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. [b]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.[/b]"[/quote]
I think this right here is what most adults have a problem with.  Some parents want their kids to get to the most advanced level as quickly as possible, so they don't like it when kids have to spend weeks understanding what should be an easy math concept.

Also, too many adults have the mentality of "this is how I learned it, and it was good enough for me to take calculus in 11th/12th grade so why can't my kids learn it the same way".  Well, because even though *you* may have learned it one way and did well doesn't mean many others did.  Americans just generally suck at math, including adults, and even our teens these days don't do as well in the critical thinking section of standardized tests compared to other countries:

"* Stagnation. U.S. scores on PISA exams haven’t improved over the past decade. See here. That’s a bit of a contrast from the NAEP exam where American students have been showing modest improvement.[u] I believe the NAEP exam plays to U.S. strengths of simple equation solving.[/u][u] It has fewer word problems where students have to apply their knowledge to a new circumstance and write their own equations and models.[/u]"[/quote]

Common Core "standards" are making the math illiteracy in this country much much worse.

And now we have the test results to show it.[/quote]

Way to wave the banner of ignorance. That article is commenting on test scores from 2003-2012. Common Core standards weren't implemented in most schools until the 2013-2014 school year, so they have absolutely nothing to do with the lack of improvement in student performance, except to the extent they were a response to how poorly we perform.[/quote]
