The study of measurement is crucial in the second grade mathematics
curriculum because of its practicality in so many aspects of
everyday life. Measurement is the assignment of a numerical
value to an attribute of an object. In the earliest grades, students
can compare and order objects using language such as longer and
shorter.
Second graders at the end of the year should master the following
measurement objectives:
Identify and use measurement
units to measure, to the nearest unit, length (i.e., inch,
centimeter), weight in pounds, and capacity in cups.
Estimate and measure length by
iterating a nonstandard or standard unit of measure.
Use different units to measure
the length of the same object and recognize that the smaller the
unit, the more iterations needed to cover a given length.
