Rows × columns sets the number of spaces per page. Problems fill across each row, then move down. Fewer rows leave more writing space. With repeats on, every space is filled. With repeats off, each selected fact appears at most once per worksheet; unused spaces stay blank and the layout stays the same. By default, each worksheet starts at 1 and is generated independently. Continue numbering treats the pages as one set; with repeats off, facts are used once across that set. If you select more facts than fit, a subset is used. Free for home and classroom practice.
