Circle every multiple of the number in the box.
Listing multiples is recall; picking them out of a row is recognition. These free printable worksheets show a number in a box and six candidates, and the child circles every one that belongs.

The answer key prints on a separate page.
Most of the row is a real rejection, so every number has to be tested rather than matched to a remembered list. Testing is the useful skill here. Knowing that 32 is a multiple of 8 because 8 × 4 = 32 is what later makes common multiples and fractions with unlike denominators manageable.
A row can hold more than one answer, and a child who stops at the first circle will miss the rest, so it is worth saying that at the start. This is a print sheet, because a drawn ring is the answer. The numbers in the boxes run up to the Level you pick in the maker.
