Probing questions
Why did you use that graph/diagram? What does the graph/diagram reveal about the problem?
How did you decide on the scales on your graph?
Would a different scale change your conclusions?
Can you explain the pattern that is shown here? Can you explain the rule? What would you expect in the next case?
Can you explain why some of the results do not follow the same pattern?
Is your generalisation always true? How do you know? What if...?
