Multiplication as scaling worksheets

Is 3/4 × 20 more than 20, less than 20, or the same? These free printable worksheets ask that and nothing else: no product is ever calculated, because the whole skill is knowing the answer before you would have one.

What's on this sheet

“Multiplying makes it bigger” is true for every multiplication a child meets until fifth grade, and then it stops being true. This page is where it stops. A factor above one stretches the number, a factor below one shrinks it, and the sheet asks for that judgment on its own so the belief has somewhere to break.

Why this sheet works

Some factors are worth exactly one and are written as fractions — 4/4, 6/6, 10/10. A bare 1 would give itself away, and “the same” has to be a real option rather than the one nobody picks. Noticing that a fraction is a whole is part of the reading.
