Concept:Flexibility in mathematics is the ability to use multiple strategies or representations to solve the same problem, adapting to different approaches efficiently.
Explanation:Procedural fluency means knowing rules, formulas, and algorithms, and using them accurately, flexibly, and efficiently.
Flexibility is a key part of this fluency.
It involves shifting between different methods or representations when solving a problem.
For example, a student can solve a fraction problem using a number line, a pie diagram, or a numerical ratio.
Or, for a given arithmetic problem, the student uses more than one calculation strategy to find the answer.
This skill improves speed, accuracy, and deeper understanding.
Therefore, flexibility specifically refers to solving one type of problem using more than one approach.
Option A is about solving different problems from the same topic – that is versatility, not flexibility.
Option B mixes different topics – that is not the definition.
Option D focuses on accuracy and writing steps – that is procedural skill, not flexibility.
Answer:C. ability to solve a particular kind of problem using more than one approach
