Scary Reunion
Anchor Papers:
Problem Solving
apprentice
Problem Solving Rationale
<p>The student’s strategy of constructing a graph to show the location of each shark would work but the student does not correctly plot the points nor calculate the actual distance traveled. The students answers of “a team of marine biologists will need to travel 45 miles per hour to be in the same location of shark 1” and “the marine biologists will need to travel 51 miles per hour to see shark 2” are incorrect. </p>
Reasoning and Proof
novice
Reasoning Proof Rationale
<p>The student does not demonstrate understanding of the underlying concepts of finding the distance traveled using a coordinate plane or the Pythagorean Theorem. There is no justification for reasoning present and arguments are made with no mathematical basis.</p>
Communication Level
apprentice
Communication Rationale
<p>The appropriate use of formal math language is minimal with <i>miles per hour and graph</i>. The student makes no attempt to provide a written account of their approach for finding 45 miles per hour or 51 miles per hour.</p>
Connections Level
novice
Connections RationaleScary Reunion
<p>The student does not make a mathematical connection about their solution.</p>
Representation
apprentice
Representation Rationale
<p>The student attempts to make a coordinate graph but does not accurately plot the location of shark 1, does not include labels, does not use it to find the distance or speed traveled.</p>
