Three-Digit Tens

This subtraction worksheet introduces students to subtracting 10 from three-digit numbers using a clear horizontal format. Learners apply place-value understanding to decrease the tens digit by one while keeping the hundreds and ones places unchanged, strengthening number sense and mental computation skills.

Instructional Objectives

• Skill Focus (Grades 3-4): Subtract 10 from three-digit numbers accurately using mental math strategies.
• Conceptual Understanding (Grades 3-4): Understand how subtracting one ten affects the tens place without changing the hundreds or ones digits.
• Algebraic Reasoning (Grade 4): Recognize predictable base-ten patterns when subtracting multiples of ten from larger numbers.
• Curriculum Alignment (Grades 3-4): Supports subtraction within 1,000, place-value reasoning with hundreds, tens, and ones, and operational fluency standards.

The horizontal layout encourages efficient mental computation and helps students focus on number structure rather than algorithmic setup. Repeated practice reinforces consistent patterns, building confidence and preparing learners for more complex multi-digit subtraction that includes regrouping.

Learning Benefits

• Builds fluency with subtracting multiples of ten from larger numbers
• Reinforces strong place-value and base-ten understanding
• Encourages efficient mental math strategies
• Effective for warm-ups, independent practice, or foundational skill building

This printable worksheet provides focused, confidence-building practice that helps students master subtracting 10 from three-digit numbers while strengthening number sense and readiness for more advanced subtraction tasks.
