[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Singapore math is as Common Core as any other CCSS aligned math.[/quote]

Singapore math is a technique. CC is a set of standards. Some schools use Singapore math to reach the standard. Some use other techniques.

I wonder if the same parents who refuse to understand this are the same ones teaching their kids that Catholics aren't Christians.[/quote]

Well, if all schools who adopted CC are teaching the same strategies, [b]then you can say it's a common curriculum[/b].[/quote]

No, you can't say it, or at least you can't say it and be correct. Here are the first-grade Common Core standards for using place value understanding and properties of operations to add and subtract:

CCSS.Math.Content.1.NBT.C.4
Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, 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 and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.

CCSS.Math.Content.1.NBT.C.5
Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.

CCSS.Math.Content.1.NBT.C.6
Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90 (positive or zero differences), 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 and explain the reasoning used.

The standards do not specify which strategies the child should be able to use. The standards only specify that the child should be able to use models/drawings and strategies and explain the reasoning.

(Singapore Math is a curriculum, but otherwise I agree with that PP.)
