3rd Grade Math Mystery Worksheets

Welcome to our 3rd Grade Math Mysteries!

In Grade 3, students are introduced to multiplication and division, as well as multi-step problem solving. The math mystery activities provide real-world application for these skills, allowing students to solve multi-step puzzles involving operations, place value, and comparing larger numbers. This helps students build fluency and confidence in tackling more complex math problems while reinforcing previously learned concepts.

Common Core Standard: 3.OA.A.3 (Use multiplication and division within 100 to solve word problems).
