Answer key
What is in this set
The numbers in this set run from 10 to 99.
Every problem in it will move digits rather than compute.
A careful solution takes 1 written step on average.
The mistake this set invites most often, in 100% of the problems: one zero short.
Answers are a whole number.
Drawing 240 problems from this page produced 87 different ones, 36% — so a sheet of 20 will come back to a problem you have seen — there are only so many sensible ones of this kind.
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.
