Manage time C2.2 Make low-level inferences to calculate using time

Competency C: Understand and Use Numbers Task Group C2: Manage timeLevel: 2At this level, learners: Make low-level inferences to calculate using timePerformance DescriptorsThe learner:Calculates using numbers expressed as whole numbers, fractions, decimals, and percentagesInterprets and applies rates (e.g. $/hr, km/hr, cooking time/pound)Converts between units of time (e.g. millennia, centuries, decades, years, months, weeks, days, hours, minutes, seconds)Makes simple estimatesInterprets, represents, and converts time using whole numbers, decimals, percentages, ratios, and simple, common fractions (e.g. ½, ¼)Chooses and performs required operation(s); may make inferences to identify required operation(s)Selects appropriate steps to reach solutionsUnderstands and converts time between 12- and 24-hour clocksConverts time between time zonesUses 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 requires two or more operations, where operations are easily inferredRequires up to a few steps to completeMay be completed in more than one wayMay involve one document (e.g. table, schedule)May require converting between whole numbers, decimals, fractions, ratios, and percentages ESKARGO:Embedded Skills, Knowledge and Attitudes Reference Guide for Ontario – C2.2
