I think you're confused. The child doesn't have to understand the standards, so does it really matter if the standards are wordy? In any case, an intelligent adult can translate that &quot;wordy&quot; standard into math problems for the 2nd grader. I'll translate it for you. For this standard, a 2nd grader should be able to grasp the following:

&quot;Add within 100, including adding a two-digit number and a one-digit number&quot; 
 Example: 98+2 = 100

&quot; and adding a two-digit number and a multiple of 10&quot; 
 95 + 5 = 100

&quot;, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; &quot; 
 Can't draw the model, but you could use 100-90 = 10. That's an example of &quot;relationship between addition and subtraction&quot;.

&quot;relate the strategy to a written method and explain the reasoning used.&quot; 
 Write: I know that 90 + 10 = 100 because 9 +1 = 10, and then you put all the number in the 10's place.

&quot; Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten&quot; 
 58 + 18

&quot;one adds .. ones and ones&quot;.. 8 + 8... 
 &quot;sometimes necessary to compose a 10&quot; .. 8 + 8 using base 10 = 8 + 2 -&gt; 10 + 6 = 16 is composed of 10 in the ten's place and 6 in the one's place

This is where now it should start to make more sense to a kid why you carry over the 1 in this equation, because the 1 in the 16 is really in the ten's place. This may seem obvious to older kids or adults, but without a firm grasp of number places, it doesn't make sense to a 2nd grader why you carry over the one.

Yea, it's wordy, but in layman's terms, it just means the kid should be able to add two digit numbers up to 100 and understand how to use number places to achieve it. [/quote]

Gee.  I can't believe you really think people are so stupid.  It took you half a page to write that.  Imagine how this works in first grade.
