[quote=Anonymous][quote=Anonymous][quote=Anonymous]If you are using a number line to subtract 3 digit numbers from 3 digit numbers. something is wrong.  KISS is my motto.[/quote]

The crutch of the Common Core BS is that students should have a deeper understanding.  My father-in-law who was a theoretical physicist always said 2 + 2 = 4.  You can prove it with diagrams and models or you can just memorize the math fact.  Memorizing to solve math problems is faster and works for the needs of the majority of students who take those skills into adulthood.  99% of the population will never have to go through life proving why math works.  It is more important to spend education dollars teaching basic math skills so math can be done quickly without aids such as calculators and number lines.

Memorization of basic math facts IS a requirement of the Common Core objectives.

Grade 2:

CCSS.MATH.CONTENT.2.OA.B.2
Fluently add and subtract within 20 using mental strategies.
[b]By end of Grade 2, know from memory all sums of two one-digit numbers[/b].

Grade 3:

CCSS.MATH.CONTENT.3.OA.C.7
Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.

Grade 4:

CCSS.MATH.CONTENT.4.NBT.B.4
Fluently add and subtract multi-digit whole numbers using the standard algorithm.

Any worksheet, teacher, school district, or website that tells you "Common Core" doesn't require fluency in basic math facts, or the ability to use "Standard algorithms" to solve problems efficiently, is incorrect.  Or, deliberately lying.[/quote]
