Graphs display lengths, not locations

Students are frequently asked to reason about graphs that they see as geometric shapes, insteadof representations that show the relationship between two quantities. This study shows aninstructional intervention, using the theory of multiplicative objects (Saldanha and Thompson,1998) that has great potential for orienting students to the quantities involved and theirrelationships, by focusing on how graphs display orthogonal lengths whose magnitudes aremeasures of quantities.Key words:
