Oh, please, at 6 years old that's the only thing you should know.

Doubles is an irrelevant, hardly useful trick for addition and we should not be spending all this time on learning doubles.  [b]We should be spending this time on learning how to add and subtract double digit numbers.[/b]  Then maybe kids will be able to count the change in their pocket in the second grade.

I'm beginning to think that this is what the school's math curriculum is - a set of tricks with lack of solid foundation.

Like this, you mean?

CCSS.Math.Content.2.NBT.B.5
Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.

CCSS.Math.Content.2.NBT.B.6
Add up to four two-digit numbers using strategies based on place value and properties of operations.

CCSS.Math.Content.2.NBT.B.7
Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.

As it happens, the Common Core standards for counting money are also for second grade (though I do wonder how many second-graders have change in their pockets):

CCSS.Math.Content.2.MD.C.8
Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately. Example: If you have 2 dimes and 3 pennies, how many cents do you have? [/quote]
