Remarks/ExamplesUsing various circular objects, students determine that the ratio of circumference to diameter approximates the value of Pi.
TEST ITEM SPECIFICATIONS
- Reporting Category: Geometry and Measurement
This benchmark will be assessed using:
Also assesses MA.6.A.3.4 Solve problems given a formula.
- Clarification :
Students will use 22/7 or 3.14 as an approximation for to determine the approximate circumference and area of circles.
Students will find the diameter or radius, given the circumference or area of a circle.
- Content Limits :
Items may include using vocabulary such as radius, diameter, and center.
Item graphics or options may include the use of visual representations or vocabulary associated with a circle, such as chord, arc, sector, and central angle. These terms will not be directly assessed.
- Stimulus Attributes :
Items may be set in a real-world or mathematical context.
Graphics should be used in most of these items, as appropriate.
- Response Attributes :
Multiple-choice responses should include only correct units (e.g., answers for area questions should all have square units).
