Vertical Twenties

This subtraction worksheet provides structured vertical practice subtracting 20 from two-digit numbers. Learners align digits carefully and compute each difference, reinforcing place-value reasoning, accuracy, and confidence with written subtraction.

Instructional Objectives

• Skill Focus (Grades 2-3): Subtract 20 from two-digit numbers using correct vertical subtraction techniques.
• Conceptual Understanding (Grades 2-3): Understand how subtracting two tens affects the tens place while the ones place remains unchanged.
• Algebraic Reasoning (Grade 3): Recognize and apply base-ten patterns when subtracting multiples of twenty.
• Curriculum Alignment (Grades 2-3): Supports subtraction with multiples of twenty, vertical computation, place-value understanding, and computational fluency standards.

The vertical format encourages organized work habits and helps students internalize the structure of two-digit numbers. Repeated exposure strengthens fluency and prepares learners for more advanced multi-digit subtraction tasks that require regrouping.

Learning Benefits

• Builds accuracy through consistent digit alignment
• Reinforces strong place-value and base-ten understanding
• Strengthens fluency with subtracting multiples of twenty
• Effective for independent practice, review, or skill reinforcement

This printable worksheet offers clear, confidence-building practice that helps students master subtracting 20 from two-digit numbers while developing solid written computation skills.
