The Purpose of a Diagram

What's your take here? Does it matter if the tape diagram attempts to represent the size of the relationships? Does it matter if it's the student's or the teacher's model?



I Personally think that diagrams should be fairly true, or be labelled as "Not to Scale" with explicit instructions to consider re-drawing the diagram in any such case.
