III. Extra Credit
The most relevant part of Common Core-inspired goals indexed at the top of the PSSA problem (goals B-0.1.1.2 and B-0.1.1.1) is: "interpret numerical expressions without evaluating them."
Discuss the comparative difficulty of this task as compared with the modeling challenge presented by the Singapore Math problem.
Which of these problems exhibits traces of the confusion between teaching math skills vs. teaching math education skills?
