[quote]It wastes the teacher's time and the student's time to gain a thorough understanding of math? [/quote]

So, a wordy standard that requires multiple testing steps is worthwhile?
  
How does that help a child understand?  Have you ever even taught school?

Yes, I have taught school, and I have tutored math.

Are we still talking about this standard?

"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"

This standard is the difference between the magic formula of "add the right-most column; if the sum is between 0 and 9, then write down the sum in the right-most column below the line; if the sum is 10 or bigger, write the right-most number of the sum in the right-most column below the line and put the 1 at the top of the next column, then add the next column and write down the sum below the line; there's your answer" and actually understanding what you're doing when you're adding and subtracting (within 100).

If all you know is the magic formula, then you can add the numbers and get the right answer. But do you understand math? Nope.

(And before somebody jumps in -- the Common Core standards also call for fluency in the using the magic formula, except that if you understand math, it's not a magic formula, it's the standard algorithm.)[/quote]
