Competency C: **Understand and Use Numbers**

Task Group C3: **Use measures**

Level: **3**

At this level, learners: **Use measures to make multi-step calculations; use specialized measuring tools**

**Performance Descriptors**

The learner:

- Calculates using numbers expressed as whole numbers, fractions, decimals, percentages, and integers
- Calculates the radius, diameter, and circumference of circles
- Understands and uses properties of angles and triangles to solve problems
- Understands and uses formulas for finding the perimeter, area, and volume of non-rectangular, composite shapes
- Manages unfamiliar elements (e.g. context, content) to complete tasks
- Makes estimates involving many factors where precision is required
- Interprets and represents measurements taken with specialized tools (e.g. callipers, multimeters)
- Chooses and performs required operations; makes inferences to identify required operations
- Selects appropriate steps to solutions from among options
- Identifies a variety of ways to complete tasks
- Interprets, represents, and converts measures using whole numbers, decimals, percentages, ratios, and fractions
- Organizes and displays numerical information (e.g. graphs, tables)
- 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)
- Requires multi-step calculations where one step builds on the previous step
- Requires the use of rates or common formulas or both
- May require converting measurements to make calculations
- May involve documents (e.g. rate tables, scale drawings)
- May require converting between whole numbers, decimals, fractions, ratios, and percentages
