“4. Use place value understanding to round decimals to any place.”
There are lots of ways to break ties.
http://en.wikipedia.org/wiki/Rounding#Tie-breaking
I’m going to go ahead and ask a question, and give what I presume is the response.
Q: Is there any preference for a particular form of tie-breaking from the standards?
A: The standards don’t specify, so it would be up to the assessment writers. If they are doing a good job, they won’t ask a question that requires a student to decide whether 2.5 rounds to 2 or to 3 because the standards don’t take a stance.
Some commentary on this in the Progressions might be appreciated.
