Solve the Riddle

This regrouping worksheet blends multi-digit addition and subtraction practice with a fun mystery riddle to boost engagement and motivation. Learners solve each problem using accurate regrouping across place values, then apply a letter-matching code to uncover the final riddle answer.

Instructional Objectives

• Skill Focus (Grades 3-5): Solve multi-digit addition and subtraction problems that require regrouping across place values.
• Conceptual Understanding (Grades 3-5): Apply borrowing and carrying strategies accurately while maintaining place-value alignment.
• Algebraic Reasoning (Grades 4-5): Use problem-solving logic to match numerical answers with coded letters.
• Curriculum Alignment (Grades 3-5): Supports multi-digit computation, regrouping strategies, problem solving, and accuracy standards.

The riddle format encourages students to check their work carefully, as incorrect computation leads to incorrect letters. This built-in feedback promotes independence, persistence, and attention to detail.

Learning Benefits

• Increases engagement through a game-like challenge
• Reinforces accuracy and self-checking habits
• Encourages independent problem solving
• Effective for practice, enrichment, or early finishers

This printable worksheet provides motivating, skill-rich practice that helps students master multi-digit regrouping while enjoying a problem-solving riddle challenge.
