Two-digit by two-digit multiplication, laid out in columns with room for the partial products underneath. Both numbers run from 10 to 99, so every problem needs the full standard algorithm rather than a fact a student might already know.
This is where the place-value zero in the second partial product goes missing, and it shows up as a consistent, wrong-by-a-factor-of-ten answer rather than random errors. Turn the answer key on and that pattern is quick to spot across a page.
Usually introduced in fourth grade and expected to be fluent by the end of fifth.
Yes - set Number of Digits to 1 in the second value range and the first stays at two digits.
Twenty is the default here because each problem takes several lines of working. Half Page cuts that to a sheet a student can finish quickly.
Turn on Include Answer Pages and a matching sheet prints behind each worksheet page, with the problems in the same order.
