29ID: A
30. ANS:
Possible explanation: I can draw two circles and divide one into four equal
parts and the other into three equal parts. Then I shade 3
of the first circle
4
and 2
of the second circle. I can see that more of the circle that is divided
3
into fourths is shaded, so 3
> 2
. Moira swam the greater distance.

PTS: 1
DIF: average
REF: Lesson 52: Compare Fractions Using Benchmarks
OBJ: Compare fractions using benchmarks.
NAT: CC.4.NF.2 Compare two fractions with different numerators and
different denominators, e.g., by creating common denominators or
numerators, or by comparing to a benchmark fraction such as 1/2.
Recognize that comparisons are valid only when the two fractions refer to
the same whole. Record the results of comparisons with symbols >, =, or <,
and justify the conclusions, e.g., by using a visual fraction model.
TOP: Extend understanding of fraction equivalence and ordering.
KEY: benchmark
NOT: Number and Operations - Fractions
