Grade 2 - Shape and Space

Standard 2.SS.1 - Compare the length of different objects determining which is longer or shorter.

Included Skills:

Demonstrate understanding of non-standard units for linear measurement by:
describing the choice and appropriate use of non-standard units
estimating
measuring
comparing and analyzing measurements.
Defend the choice of a non-standard unit for measuring a length in a situation relevant to one's self, family, or community.
Estimate a personally relevant length, including the distance around a space, using one's own choice of standard unit.
Compare estimates of the same length made by different units and provide reasons for different values being stated for the measurements.
Critique the statement "It is possible to get an exact length measurement".
Devise and apply strategies for determining estimates for linear and non-linear lengths using non-standard units.
Explain why overlapping or leaving gaps does not result in accurate measurements.
Explain why the same non-standard unit should be used to determine length measurements that are to be compared.
Compare and order sets of related objects, possibly including people, according to a length measurement.
