What is in this set

The numbers in this set run from 1 to 8.
Every problem in it will come out column by column with nothing carried.
A careful solution takes 1 written step on average.
The mistake this set invites most often, in 100% of the problems: the two numbers were subtracted instead of added.
Answers are a whole number.

Drawing 240 problems from this page produced 36 different ones, 15% — so a sheet of 20 will come back to a problem you have seen — there are only so many sensible ones of this kind.

The same skill, harder or easier

We would put this in front of a grade 1 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.
