Competency C: Understand and Use Numbers
Task Group C1: Manage money
Level: 3

At this level, learners: Find, integrate, and analyze numerical information to make multi-step calculations to compare cost options and prepare budgets

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 the task
• Chooses and performs required operations; makes inferences to identify operations
• Selects appropriate steps to reach solutions from among options
• Identifies a variety of ways to complete the task
• Finds, integrates, and analyses numerical information
• Organizes and displays numerical information (e.g. tables, graphs)
• Makes estimates
• 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)
