Grade 3 - Shape and Space

Standard 3.SS.4 - Practice finding the appropriate weight of various objects. Understand the approximate scale of different metric units.

Included Skills:

Demonstrate an understanding of measuring mass (g, kg) by:
• selecting and justifying referents for the units g and kg.
• modelling and describing the relationship between the units g and kg.
• estimating mass, using referents.
• measuring and recording mass.
• Provide a personal referent for one gram, and explain the choice.
• Provide a personal referent for one kilogram, and explain the choice.
• Match a given standard unit to a given referent.
• Explain the relationship between 1000 g and 1 kg, using a model.
• Estimate the mass of a given object, using personal referents.
• Determine and record the mass of a given 3-D object.
• Measure, using a scale, and record, using the units g and kg, the mass of given everyday objects.
• Provide examples of 3-D objects that have a mass of approximately 1 g, 100 g and 1 kg.
• Determine the mass of two given similar objects with different masses, and explain the results.
• Determine the mass of an object, change its shape, re-measure its mass, and explain the results.
