North Carolina unpacking the standards:
Before considering the relationship of decimal fractions,
students express their understanding that in multi-digit whole numbers, a digit
in one place represents 10 times what it represents in the place to its right
and 1/10 of what it represents in the place to its left.
------------------------------------------------------------------------------------------------------------
Darke School District (Ohio):
I can look at a multi-digit number and determine that the digit
to the left is 10 times greater than a given digit.
I can determine that in a multi-digit number, a digit to the
right is 1/10 of the given digit.
------------------------------------------------------------------------------------------------------------
CCSS website:
CCSS.Math.Content.5.NBT.A.1 Recognize that in a multi-digit
number, a digit in one place represents 10 times as much as it represents in
the place to its right and 1/10 of what it represents in the place to its left.
------------------------------------------------------------------------------------------------------------
Align, Assess, Achieve: (flip book)
I can recognize that each place value to the left is 10
times larger in a multi-digit number.
I can recognize that each place value to the right is 1/10th
as much in a multi-digit number.
------------------------------------------------------------------------------------------------------------
NOW - I realize that all are correct...but I highlighted what the students see. Is this what they are getting at when say "rigor?" Or is it just semantics...
Which way makes more sense to you?
