Tracking Height and Weight Percentiles

Competency C: Understand and Use Numbers
Task Group C4: Manage data
Level: 3
At this level, learners: Find, integrate, and analyze data; identify trends in data

Performance Descriptors
The learner:

• Calculates using numbers expressed as whole numbers, fractions, decimals, percentages, and integers
• Manages unfamiliar elements (e.g. context, content) to complete tasks
• Makes estimates involving many factors where precision is required
• Begins to recognize bias in data and in displays, such as graphs
• Calculates and interprets summary measures (e.g. mean, median, mode)
• Calculates percent change
• Applies statistics (e.g. population change, growth rates)
• Chooses and performs required operations; makes inferences to identify required operations
• Selects appropriate steps to solutions from among options
• Interprets, represents, and converts values using whole numbers, decimals, percentages, ratios, and fractions
• Identifies a variety of ways to complete tasks
• Finds, integrates, and analyses data
• Organizes and represents numerical information (e.g. tables, graphs)
• Makes predictions using data; identifies trends
• Uses strategies to check accuracy (e.g. estimating, using a calculator, repeating a calculation, using the reverse operation)

Task Descriptors

• Scope of task may not be clearly defined
• May include unfamiliar elements (e.g. context, content)
• May require two or more operations; operations must be inferred
• Requires multiple steps to complete
• Has many options to complete; does not have a set procedure
• May require calculating rates
• May involve documents (e.g. tables, graphs)
• May require converting between whole numbers, decimals, percentages, ratios, and fractions
