Subtraction Station Worksheet Within 20 for 1st Grade

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.

What students will practice

• Subtract within 20
• Solve problems written across the page
