My student is constantly off task

Challenge
My student is constantly off task

Scenario:
One of the challenges I am faced with when working with my student is that he often talks off subject, especially when he doesn’t know the answer to the question I asked him. Instead of answering it, he begins to speak about something that heknows about. I usually try to rephrase the question, help him with the answer, or move on to the next question.

Possible Strategies:
If the student is having trouble with comprehending readings, make sure you clarify the vocabulary and then ask the questions. The student will then probably have a better chance at answering the questions.
