About this worksheet
Fourteen subtraction problems within 20, written across the page with an answer box at the end of each line. They range from gentle ones like 11 − 2 to problems that cross ten, like 12 − 9 and 16 − 9.
Writing subtraction across the page (13 − 5 = ?) is how children meet it in number sentences and word problems, so it is worth practicing alongside the vertical form.
A friendly hedgehog with a pencil sits at the top, and the whole page prints in black and white.
