What is in this set

The numbers in this set run from 2 to 9.
Every problem in it will take one step.
A careful solution takes 2 written steps on average.
The mistake this set invites most often, in 96% of the problems: the two lengths were multiplied — that covers the garden; a fence goes round the edge of it.
Answers are a whole number.

Drawing 240 problems from this page produced 56 different ones, 23% — 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.
