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:

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.
