With an eye on the strength and coherence of mathematical arguments, we will discuss the quality of mathematical arguments that grades 1–8 PSTs’ formulate in “constructing” and “critiquing” mathematical arguments situations. We examined PSTs' arguments with a focus on four dimensions: completeness and correctness of conclusion, conceptual reference on which the argument rests, sufficiency of evidence, and sufficiency of the reasoning that justifies that the evidence supports the claim.
