Competency C: Understand and Use Numbers
Task Group C3: Use measures
Level: 1
At this level, learners: Measure and make simple comparisons and calculations

Performance Descriptors
The learner:

• Adds and subtracts whole number measurements
• Recognizes values in number and word format
• Recognizes simple, common shapes (e.g. circle, square, rectangle, triangle)
• Measures distance, length, width, height, weight, liquid volume, angles, and temperature
• Uses common measuring tools, such as rulers, scales, and thermometers
• Understands numerical order
• Makes simple estimates
• Begins to interpret integers (e.g. temperature, elevation)
• Chooses appropriate units of measurement (e.g. centimetres, metres, kilometres)
• Uses common standard units (e.g. metres, inches) and non-standard units (e.g. paces, cupfuls, scoops)
• Identifies and performs required operation
• Interprets and represents measures using whole numbers, decimals, and simple, common fractions (e.g. ½, ¼)
• Interprets and represents measures using symbols and abbreviations (e.g. inches as “, centimetres as cm, pounds as lbs, kilograms as kilos or kg)
• Follows apparent steps to reach solutions
• Rounds to the nearest whole unit (e.g. kilos)
• Uses strategies to check accuracy (e.g. estimating, using a calculator, repeating a calculation, using the reverse operation)

Task Descriptors

• Has a concrete and familiar context
• May require adding or subtracting measurements; operation is apparent
• May require the same operation to be performed more than once
• Requires up to a few steps to complete
• Has a set procedure
