Mass
Overall Expectations
Students will:
• Estimate, measure, and record length, perimeter, area, mass, capacity, volume, and elapsed time, using a variety of strategies
(4m38)
• Determine the relationships among units and measurable attributes,including the area and perimeter of rectangles (4m39)
Specific Expectations
Students will:
• Estimate, measure, and record the mass of objects, using the standard units of the kilogram and the gram (4m45)
• Compare and order a collection of objects, using standard units of mass (i.e., gram, kilogram) and/or capacity (i.e., millilitre, litre)
(4m52)
• Determine, through investigation, the relationship between grams and kilograms (4m53)
• Select and justify the most appropriate standard unit to measure mass (i.e., milligram, gram, kilogram) and the most appropriate
standard unit to measure the capacity of a container (i.e., millilitre, litre) (4m55)
