The heading here, Multiplication Minute, frames the 21 problems as a single timed run. Problem text is set in a noticeably heavier semi-bold weight, the darkest of the seven drill pages, which helps a child who is still reading numerals with care. A square double-line frame encloses the grid of seven rows and three columns, numbered 1 to 21 down each column, with a short blank after every equals sign.
Pair it with a stopwatch when you want a fluency check rather than untimed practice, and note the run on the Date rule so you can compare attempts later. Because the facts are the same 2s through 9s that the other sheets in this set cover, a faster or slower minute reflects the child rather than a change in the page.
