It sounds like your son was being taught to do this, and it seems like a valid real-world skill. Hooray, 2.0!
What is this new math invention ushered in with curriculum 2.0? Rounding and estimation is not new it's as old as the Colonies my dear.
Exactly, so not sure what P-PP is complaining about!

There was no textbook for me to refer to nor did it connect to anything that came home prior. Obviously it was an extension (hard as crap) but it wasn't relevant for my son because it did not build upon anything he had been taught prior.
Basically, it was a worksheet that showed two additional ways of doing long subtraction. My son learned long subtraction 2 years ago and kept wanting to use that method but it wasn't what was demonstrated on the top of the worksheet. It wanted him to estimate subtraction, add in the difference of what you estimated, then add with estimating and putting in the difference and checking the answers which should be the same. Sheer craziness. This for a 3rd grader.
My son finally, after several tries could do the problems independently but then asked the logical question, why would anyone do math this way? Why not just solve the subtraction problem using long subtraction techniques. I'm thinking yep, my son is right. The old way was good enough for thousands of years. Why is MCPS trying to re-write math?
What the PP maybe doesn't know is that the content is different. The Common Core standards are different than the old standards were, so while there may be some overlap, other things are new. If this year's 3rd graders in her example skipped to 4th grade common core this year, there would be holes between the 2 different sets of standards.
Its not worthy of a response

I'm not sure what this means. no takers?

I can see why some children and their parents might be frustrated. I guess they really couldn't figure out any other way, but to have them repeat. It has to happen at some point I guess, but the teachers should make more of an effort to present new worksheets at least and give some side extensions to the advanced kids to keep them excited about math.
2.0 is a new curriculum developed by MCPS to implement and meet the new standards under the Common Core Standards that were adopted by the state of Maryland and 47 other states. The standards for each grade changed, therefore, what is being taught in each grade must change. So, MCPS developed its own curriculum rather than buying one "off the shelf." MCPS plans to sell the curriculum to other schools systems.
