Hmmmm. I guess close is good enough huh? You won't need to know the "actual" answer because you won't need to use it for anything icky like a job or something that puts constraints on your free time. Who buys into this crap???? I got a fairly "unreasonable" answer for these idiots.

It's a worksheet on using estimation to make sure the real answer is in the right range. In this case the problem is 354+291=645, with an estimate of 300+200=500. I disagree with the rounding of 291 down to 200 when it should be rounded up to 300 giving an estimate of 600. But estimation is a valid technique for making sure that the real answer is just horribly wrong and for real life when you need to do something like estimate how much fertilizer you need (since you can't buy 6.47839 bags, 7 is a good enough answer).
It's even more important in multiplication when one mistake can get an answer an order of magnitude away from the real answer.

If you have a younger relative enrolled in one of these so called core systems, do them a favor for the rest of their lives..
Enroll them in Kumon learning center and pay for them to learn how to do math.

One of our younger relatives became the village idiot in math in his Californicator school.
This is inspite of his gene pool on both sides having high math processors.
His parents enrolled him in a Kumon math tutoring class. In a couple of months, he went from village idiot to doing real math two+ grades ahead. He became a member of the Math Olympics and still is a member.

Close enough is good enough for government work. And since all the products of Common Core will be working for the government, why give them more than enough?

I observed an entire family in a restaurant trying to puzzle through just such a worksheet with their child. There was a grandmother, grandfather, mother, and a 9 year old boy. The book they were using was called “California Math”, which was offensive right there.
I couldn’t see what they were doing, but the grandfather worked on the problem for about an hour, muttering things like, “What is this estimate thing?” and “You cannot round up 229 to 300. That’s just not right!”
Sheer abuse by the educators.

This so called ‘estimate’ didn’t even use the rules of rounding correctly.
The old fashion drill and kill method of learning ones ‘tables’ did more to help teach arithmetic (which this is....it is not ‘mathematics’ as such).
We wonder why people can’t do calculations when their quackulator dies and we now know why.
This is malfeasance of the highest order

New, new, new, new, math?
Completely negates conventional number theory and thus, the ability to learn ANY advanced maths. Good bye future engineers, hello degradation into the stone age. Humans who actually get past this idiocy will be called “mage” or “magister.”
Pretty scary.

In math we are dealing with absolutes: 2 + 2 = 4 and not 5 or three or “reasonable - learning in progress”.
“Reasonable” is only good for horse shoes, hand grenades, and nuclear weapons.
