0-20 Subtraction

Worksheet Description

This worksheet is a straightforward educational tool for practicing single-digit subtraction, with all numbers involved ranging from 0 to 20. It presents a series of horizontal subtraction problems, each consisting of a two-digit number from which a single-digit number is to be subtracted. The students are required to calculate the differences and write their answers in the blanks provided next to each problem. At the bottom of the worksheet, there is a “How Did You Do?” section with emoticon faces ranging from happy to sad, allowing students to self-assess their performance.

The worksheet is designed to help students develop proficiency in basic subtraction facts within the range of 20, which is a fundamental aspect of early mathematics education. By solving these problems, students enhance their mental arithmetic skills and their understanding of the concept of ‘taking away.’ The variety of problems also helps students to become more comfortable with subtracting across the entire span of single-digit numbers. The addition of the self-assessment section promotes reflective learning, as students are encouraged to think about how they feel regarding their mastery of the subtraction problems.
