[quote=Anonymous][quote=Anonymous]But, why?[/quote] This isn't a major philosophical problem here. The standard is asking 2nd grade students to know that 36 is 3 tens and 6 ones, and that 23 is 2 tens and 3 ones; and that you add them together and get 5 tens and 9 ones, or 59. There's no more to the standard than that (or possibly also including regrouping.) That's using place value to add. (Instead of counting on 23 times.) Perhaps the standard should be reworded since it is causing you so much difficulty; into two separate standards. Other states have had these standards for the same principle: [quote] Understand and use place value to solve two digit additions and subtraction problems Understand and use the inverse relationship between addition and subtraction to solve problems and check solutions [/quote] However, you would need to observe a child adding and subtracting individually to be certain he or she was using place value (and not just counting on repeatedly) [/quote]
