Which one of the following questions is open ended?

Correct option is C

An open-ended question allows for multiple correct responses, encouraging students to think critically and creatively. It does not have a single, definitive answer and promotes exploration of different possibilities.
· Option (c): "Write any two numbers whose product is 45" is an open-ended question because there are multiple pairs of numbers that can be multiplied to produce 45 (e.g., 9 × 5, 15 × 3, 45 × 1). This question allows students to provide various correct answers.
In contrast:
· Option (a): "Find 15 × 3" has a single correct answer (45).
· Option (b): "How will you multiply 15 by 3?" is more procedural and typically leads to one correct method.
· Option (d): "Use a number line to find 3 times 15" also leads to a specific solution (45).
Hence, the correct answer is (c) Write any two numbers whose product is 45.
Information Booster:
1. Open-ended questions foster creativity and deeper thinking, as students can approach the problem from different angles and present various solutions.
2. They are commonly used in inquiry-based learning environments to encourage exploration and discussion.
3. Closed-ended questions often have a single, fixed answer, which tests factual knowledge or specific procedures.
4. Open-ended questions help develop critical thinking, problem-solving, and reasoning skills, making them valuable in teaching mathematics.
Additional Information:
· Encouraging students to engage with open-ended questions promotes a more dynamic and interactive classroom experience, where they are not just focused on finding the "right" answer but exploring various solutions and methods.
