[quote=Anonymous][quote=Anonymous]I have a 2nd grader and they're not allowed to carry numbers in math.  I'm baffled why that's not allowed.

I think part of the reason is to make sure they understand ones, tens, hundreds.  But it seems to make the procedures so much more complicated.

For example, if the problem is 45+57, they don't start on the right and add 5+7 and then 4+5, carrying the 1.  They do 40+50, then 5+7, then 90 +12.  But supposed to do it in their head, which isn't going to work as the problems get more complex. And my other child is taught to draw boxes and dots to represent the ones, tens and hundreds.  One problem could take 5 minutes.

Does this change in higher grades? Are other schools not allowing kids to carry and add and subtract starting from the right?

My daughter is in 5th and it has really slowed down their math learning.  They spend so much time on simple math and then try to quickly move on once they get in 3rd and realize from standardized test, they need more.  For kids that aren't good in math, it helps.  For most kids though, that know numbers, adding etc... by kindergarten,  it is 3 years of monotony that isn't showing up to higher test scores.  Why do you think they are getting rid of final exams and rounding up grades?  Math is taught to the lowest common denominator.  [/quote]
