Vertical Subtraction by 8s

This subtraction worksheet provides focused vertical practice subtracting 8 from numbers between 10 and 19. Learners compute each difference and record answers in designated boxes, reinforcing correct digit alignment, neat work habits, and accuracy while strengthening fluency with a challenging subtraction fact set.

Instructional Objectives

• Skill Focus (Grades 1-2): Subtract 8 from teen numbers accurately using vertical subtraction.
• Conceptual Understanding (Grades 1-2): Strengthen number sense by recognizing patterns that emerge when subtracting 8 from consecutive numbers.
• Algebraic Reasoning (Grade 2): Identify and apply counting-back strategies to improve efficiency with larger single-digit subtrahends.
• Curriculum Alignment (Grades 1-2): Supports subtraction fact fluency, mental computation strategies, number pattern recognition, and vertical algorithm practice.

The consistent structure helps students internalize subtraction patterns involving 8, which are often more difficult than smaller facts. The vertical format supports correct setup and reduces common alignment errors while encouraging independent practice.

Learning Benefits

• Builds fluency and confidence with subtraction facts involving 8
• Reinforces mental math strategies and pattern recognition
• Encourages neat, accurate vertical computation
• Effective for independent practice, review, or targeted intervention

This printable worksheet delivers focused, confidence-building practice that helps students master subtracting 8 from teen numbers while strengthening foundational subtraction skills and number sense.
