Answer key
What is in this set
The numbers in this set run from 1,028 to 9,957.
Every problem in it will need a borrow from the column to the left.
A careful solution takes 5 written steps on average.
The mistake this set invites most often, in 100% of the problems: each column took the smaller digit from the larger one instead of borrowing from the column to its left.
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 4 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.
