Withdrawal by 8s and 9s

This subtraction worksheet provides structured practice subtracting 8 or 9 from teen numbers using a clear vertical format. Learners record answers in designated boxes, supporting neat work, correct digit alignment, and accuracy while strengthening fluency with challenging subtraction facts.

Instructional Objectives

• Skill Focus (Grades 1-2): Subtract 8 and 9 from numbers within 20 using accurate counting-back strategies.
• Conceptual Understanding (Grades 1-2): Develop number sense by recognizing relationships between teen numbers and larger single-digit subtrahends.
• Algebraic Reasoning (Grade 2): Identify patterns in subtraction facts involving 8 and 9 to support efficient mental math.
• Curriculum Alignment (Grades 1-2): Supports subtraction within 20, number sense development, mental math fluency, and written vertical computation standards.

The repeated structure allows students to internalize fact families involving 8 and 9, which are often more challenging than smaller subtrahends. Vertical alignment reinforces correct setup while encouraging careful, independent work.

Learning Benefits

• Builds fluency with difficult subtraction facts
• Strengthens counting-back and mental math strategies
• Reinforces neatness and accuracy in written computation
• Effective for practice, intervention, or foundational skill building

This printable worksheet provides essential practice that helps students gain confidence subtracting 8s and 9s from teen numbers while strengthening number sense and readiness for more advanced subtraction.
