Subtract by 8s and 9s Worksheets

About This Worksheet Collection

This collection of subtract-by-8s and subtract-by-9s worksheets gives students focused, high-value practice with two of the most challenging single-digit subtraction fact families. Across vertical, horizontal, and mixed layouts, learners work repeatedly with subtraction problems that require efficient counting-back strategies and strong number sense. The clean formatting and structured answer boxes help minimize distraction, encouraging students to concentrate on accuracy, alignment, and mental-math recall.

As students progress through this set, they strengthen their fluency with subtracting 8 and 9, deepen their understanding of numerical distance, and recognize predictable patterns in these larger fact families. The worksheets support foundational skills needed for future multi-digit subtraction, algebraic reasoning, and flexible mental computation. Because each page targets a specific skill set, teachers can easily use them for warm-ups, fluency drills, centers, or intervention.

Detailed Descriptions Of These Worksheets

Withdrawal by 8s and 9s
Students practice subtracting 8 and 9 from teen numbers using vertical problems arranged with neat answer boxes. The structured layout reinforces digit alignment while helping learners focus on accuracy. Repeated fact patterns develop fluency and strengthen counting-back strategies. This worksheet supports confident mental computation and prepares students for more complex subtraction.

Vertical Subtraction by 8s
Learners solve vertical subtraction equations that all involve subtracting 8 from numbers between 10 and 19. Each item reinforces place-value alignment and neat recording. Students improve fluency by repeatedly counting back eight and recognizing predictable subtraction patterns. The page works well for independent practice or quick fluency sessions.

Vertical Subtraction by 9s
This worksheet gives students repeated vertical practice subtracting 9 from teen numbers. The consistent structure helps learners stay organized while solving more difficult subtraction facts. Students strengthen their counting-back-nine strategy and build accuracy with challenging computations. The activity supports readiness for higher-level subtraction.

Mixed 8s and 9s Removal
Students compute vertical subtraction problems that alternate between subtracting 8 and subtracting 9. The mixed format promotes flexible thinking and helps learners compare the effects of each subtrahend. Repetition encourages fluency and accurate mental math. This worksheet is ideal for warm-ups, centers, or practice sessions focused on challenging fact families.

Teen Number Decrease
Learners subtract 8 or 9 from teen numbers using vertical equations with aligned answer boxes. The repeated format reinforces careful digit placement and strengthens mental strategies for subtracting larger single-digit values. Students build fluency and develop confidence with facts that require more complex counting back.

Mixed Differences
This worksheet presents horizontal subtraction expressions involving 8 and 9, encouraging students to rely on mental computation. Learners compute each difference and write answers in clearly spaced boxes. The repetition supports strong fact recall and deepens understanding of number relationships. This page works well as a warm-up or fluency builder.

Subtracting 9s Practice
Students solve horizontal subtraction problems focused exclusively on subtracting 9 from numbers between 10 and 19. Repeated practice helps learners internalize consistent patterns and strengthens their counting-back strategy. This worksheet builds confidence with a notoriously challenging subtraction family.

Subtracting 8s Practice
Learners complete horizontal subtraction expressions that all involve subtracting 8 from teen numbers. The clear format encourages neatness and efficient computation. Students strengthen fluency by recognizing common patterns associated with subtracting eight. The repetition supports readiness for more advanced arithmetic tasks.

Columns by 8s and 9s
This worksheet features vertical subtraction problems using 8 and 9, giving students practice with alignment and precision. Structured answer boxes guide neat, organized responses. Students develop fluency with difficult subtraction facts and deepen number-sense skills. The layout makes this sheet effective for independent practice or reinforcement.

Structured Columns
Students solve vertically aligned subtraction problems involving subtracting 8 or 9 from a range of values. The consistent design helps learners focus on computation without distraction. Repeated practice strengthens their ability to count back efficiently and recognize subtraction patterns. This worksheet prepares students for more complex multi-digit subtraction.

Subtracting 8s (Vertical)
This worksheet presents teen-minus-eight subtraction in vertical form with structured answer boxes that support alignment. Learners repeatedly practice subtracting 8, reinforcing a key mental-math strategy. The clean layout encourages neat work habits and supports fluency-building.

Subtracting 9s (Vertical)
Students complete vertical subtraction problems with teen numbers minus 9, writing answers in designated boxes for accuracy. Repetition helps learners see consistent results when subtracting nine and strengthens mental computation. This worksheet supports foundational fluency needed for advanced subtraction and future multi-step operations.
