Dude see attached chart and annerberg link. Whether you agree with the chart or not, it lays it out very clearly. If the problem wanted, as an answer, a "difference" and a "subtraction" sentence, it should have asked for that and it should have instructed the student to write a "separating story" rather than a "comparing story." However, the instructions read, "Write a comparing story....Write a number sentence that solves the story." The very problem and answer DS gave as his answer is in chart as correct and a model answer!
