Measurement+Outcome+1

General Outcome: Develop spatial sense and proportional reasoning.

Specific Outcomes

1. Solve problems that involve linear measurement, using: • SI and imperial units of measure • estimation strategies • measurement strategies. [ME, PS, V]

Achievement Indicators

1.1 Provide referents for linear measurements, including millimetre, centimetre, metre, kilometre, inch, foot, yard and mile, and explain the choices.

1.2 Compare SI and imperial units, using referents.

1.3 Estimate a linear measure, using a referent, and explain the process used.

1.4 Justify the choice of units used for determining a measurement in a problem-solving context.

1.5 Solve problems that involve linear measure, using instruments such as rulers, calipers or tape measures.

1.6 Describe and explain a personal strategy used to determine a linear measurement; e.g., circumference of a bottle, length of a curve, perimeter of the base of an irregular 3-D object.
