What is in this set

The numbers in this set run from 2 to 50.
A careful solution takes 3 written steps on average.
The mistake this set invites most often, in 100% of the problems: that is the largest value; the range is the largest less the smallest.
Answers are a whole number.

Drawing 240 problems from this page produced 240 different ones, 100% — so a sheet of 20 is a new sheet almost every time.

We would put this in front of a grade 5 class. That is our judgement, not a standard, and it is printed here so you can disagree with it. Everything else we put in that year.
