The mistake this set invites most often, in 61% of the problems: the bars were ignored; they turn whatever is inside into its distance from zero, which is never negative.
Answers are a whole number.
Drawing 240 problems from this page produced 176 different ones, 73% — so a sheet of 20 is a new sheet almost every time.
We would put this in front of a grade 6 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.
