Math Games for Teachers

Grade 2 - Shape and Space

Standard 2.SS.2 - Practice finding the appropriate weight of various objects. Understand the approximate scale of different metric units.

Included Skills:

Demonstrate understanding of non-standard units for measurement of mass 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 mass in a situation relevant to one's self, family, or community.
Estimate the mass of a personally relevant object using one's own choice of standard unit.
Identify a non-standard unit for measuring mass that would not be a good choice in a particular situation and explain the reasoning (e.g., to measure the mass of a desk, it would not make sense to use an eraser as the standard unit because a desk has so much more mass than an eraser and so it would take too many erasers, or to measure the mass of a library book using the standard unit of a student in the class because the student already has a greater mass than the book).
Compare estimates of the mass of the same object determined using different standard units and provide reasons for different values being stated for the measurements.
Explain why the same non-standard unit should be used to determine mass measurements that are to be compared.
Compare and order sets of related objects according to mass measurements and explain the reasoning.
