Number Line 0 to 20, Printable PDF, Letter Landscape

By late first grade and second grade, students work across the full 0–20 fact range. A wider line keeps each integer readable without crowding the page, so this preset uses landscape Letter with two lines and labels at every whole number.

Use it for skip counting, finding differences, or showing where a sum lands before students write equations. The controls below adjust how many lines print per page, paper size, or range (including negatives).

Print at 100% — choose Actual size, not Fit to page — so one unit on paper matches one unit in your lesson.
