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.
My child in Virginia learned doubles and Virginia is not a Common Core state, so I think you are not as well informed as you think you are.

Actually doubles aren't even mentioned as a term, in Common Core. This is what is stated as an objectve for first grade, which is where you'd expect the concept of doubles and doubles plus one to be taught:

CCSS.MATH.CONTENT.1.OA.C.6
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.
Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

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."

Yes, there is an Everyday Math curriculum aligned to the Common Core standards.
There were plenty of PPs who said because I can figure it out it's just fine and one even said OP's child just must not be that good in math. Sorry to sound shrill, but poor writing in children's texts really bothers me. Such a disservice to them.
Also on the other common core thread most of the posters thought having a very language heavy math curriculum was a good thing and if kids with language problems were at at a disadvantage that just means the school should provide more supports. As if. They somewhat ridiculously divided the world into verbal and nonverbal kids and obtusely overlooked, despite multiple posts, that verbal children on the low range of normal have difficulties with language-ladened math curriculums.
Do you disagree with this?
No not at all. I followed it with "As if." Spend some time on the SN boards to see how easy it is to get supports for the really language impaired and nonverbal. Then you would understand that low normal language kids wouldn't have a chance in million at getting any support at all.
Clear language serves everyone best.

I have used Singapore Math with my 2 children, so I feel confident saying that Singapore Math works with the two children I have used it with. But I am not going to go around saying that Singapore Math works with every child, or that I am an expert in teaching math, or that Singapore Math's way is the only way.
