" Come up with a formula that will use the information that matters and then return a number to tell us who did the best and worst job drawing the midpoint."

(I would definitely do triangle & square - teacher's guide shows examining largest areas possible given the perimeter as the best solution!)

This is a table we created to organize perplexing elementary math tasks by standard.
