What is in this set

The numbers in this set run from 0.49 to 9.96.
Every problem in it will stack more than two numbers.
A careful solution takes 4 written steps on average.
The mistake this set invites most often, in 100% of the problems: the last price was never added in; a column of money is added like any other column.
Answers are an amount with two decimal places.

Drawing 240 problems from this page produced 240 different ones, 100% — 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 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.
