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]

I don't see the value of the doubles strategies.  Because you're confusing the kids.  You're giving them 3 different strategies - doubles, count on, tens and ones.

Doubles are useless because a) you can't use them in additions above 10; b) kids already pretty much memorize all the additions within 10; c) they confuse kids who are trained to use tens and ones for adding.

No one uses doubles besides CC.  Singapore math doesn't use doubles, Kumon doesn't use doubles, Critical Thinking doesn't use doubles.

My education in math was in Russia.  Russia had an excellent math education.  We never used doubles.  It's looks like a Common Core invention and it's full of crap like this.[/quote]
