Grade 3 - Measurement and Data
Standard 3.MD.1.4 - Practice finding the appropriate weight of various objects. Understand the approximate scale of different metric units.
Included Skills: Measurement
Students will be expected to demonstrate an understanding of measuring mass (g, kg) by • selecting and justifying referents for the units gram and kilogram (g, kg) • modelling and describing the relationship between the units gram and kilogram (g, kg) • estimating mass using referents • measuring and recording mass • Performance Indicators - M04.01 Provide a personal referent for one gram and explain the choice. - M04.02 Provide a personal referent for one kilogram and explain the choice. - M04.03 Match a given standard unit to a given referent. - M04.04 Explain the relationship between 1000 grams and 1 kilogram using a model. - M04.05 Estimate the mass of a given object using personal referents. - M04.06 Measure, using a balance scale, and record the mass of given everyday objects using the units gram (g) and kilogram (kg). - M04.07 Provide examples of 3-D objects that have a mass of approximately 1 g, 100 g, and 1 kg. - M04.08 Determine the mass of two given similar objects with different masses and explain the results. - M04.09 Determine the mass of an object, change its shape, re-measure its mass and explain the results.
