What is in this set

The numbers in this set run from 200 to 50,000.
Every problem in it will need the length factor used twice, because the units are square ones.
A careful solution takes 2 written steps on average.
The mistake this set invites most often, in 100% of the problems: 100 is the factor between the lengths.
Answers are a whole number.

Drawing 240 problems from this page produced 8 different ones, 3% — 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 6 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.
