Use measure C3.2 Use measures to make one-step calculations

Competency C: Understand and Use Numbers Task Group C3: Use measuresLevel: 2At this level, learners: Use measures to make one-step calculationsPerformance Descriptors The learner:Calculates using numbers expressed as whole numbers, fractions, decimals, percentages, and integersCalculates angles in simple, common shapesMakes estimatesUnderstands and uses ratio and proportionInterprets and represents area and volume using symbols and abbreviations (e.g. m3 )Interprets and applies rates (e.g. km/hr, km/l) and ratios (e.g. map scales)Converts units of measurement within the same system and between systemsUnderstands and uses formulas for finding the perimeter, area, and volume of simple, common shapesChooses and performs required operation(s); may make inferences to identify required operation(s)Selects appropriate steps to solutionsInterprets, represents, and converts measures using whole numbers, decimals, percentages, ratios, and simple, common fractions (e.g. ½, ¼)Uses strategies to check accuracy (e.g. estimating, using a calculator, repeating a calculation, using the reverse operation)Task DescriptorsScope of task is clearly definedMay include unfamiliar elements (e.g. context, content)Requires the use of rates or common formulasRequires one-step calculations, which may be repeated; operations are easily inferredMay be completed in more than one wayMay involve one document, such as a simple conversion tableMay require converting between whole numbers, decimals, fractions, ratios, and percentages ESKARGO:Embedded Skills, Knowledge and Attitudes Reference Guide for Ontario – C3.2
