What is in this set

The numbers in this set run from 2 to 12.
A careful solution takes 3 written steps on average.
The mistake this set invites most often, in 100% of the problems: the triangular end was not halved; a triangle is half of the rectangle around it.
Answers are a whole number.

Drawing 240 problems from this page produced 162 different ones, 68% — so a sheet of 20 is a new sheet almost every time.

The same skill, harder or easier

We would put this in front of a grade 8 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.
