What should you do if a student answers with fewer than three numbers?

When a student responds with fewer than three numbers, prompting them to provide additional responses is essential because the task likely aims to assess a specific cognitive ability, such as fluency or problem-solving skills. Offering encouragement can help the student engage more thoroughly with the task and may lead them to think more critically about their response.

This approach allows for a fuller and more accurate assessment of their abilities, as the task's design presumably expects a minimum number of responses to measure proficiency effectively. By providing a chance for the student to elaborate or expand their answers, you facilitate a more complete evaluation of their cognitive performance.
