What is in this set

The numbers in this set run from 2 to 55.
A careful solution takes 2 written steps on average.
The mistake this set invites most often, in 100% of the problems: an hour is 60 minutes, not 100 — the two parts cannot be written side by side.
Answers are a whole number.

Drawing 240 problems from this page produced 186 different ones, 78% — 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.
