2025 Team Competition Solutions Grades 5-6

Pdf Summary

This document is a solution summary for the 2025 Math Kangaroo USA Grades 5–6 Team Competition. It lists answers and brief reasoning for 30 problems, split into multiple choice (1–20) and short answer (21–30).<br /><br />The problems cover a wide range of elementary math and logic topics: distance and motion, counting and measuring, paper folding, cube adjacency, path tracing, place value, geometry nets, balance scales, age-order logic, color and face orientation on cubes, equations with unknown quantities, paper cutting and symmetry, sequential page-eating, grid navigation, number placement in squares, grouping numbers, Sudoku-style logic, and shape decomposition. The short-answer section includes digit-counting in a written number, area calculations, solving for unknown box values using multiplication constraints, factor/product puzzles, arrangement counting, card-flipping patterns, cube-number relationships, a digit cryptogram, perimeter of overlapping shapes, and language-counting with set logic.<br /><br />Several solutions rely on standard competition strategies:<br />- comparing positions and symmetries,<br />- using elimination and casework,<br />- applying algebraic equations,<br />- counting with combinations and patterns,<br />- and checking all answer choices against constraints.<br /><br />The final answers given are:<br />1 D, 2 B, 3 C, 4 C, 5 E, 6 A, 7 B, 8 D, 9 A, 10 A, 11 D, 12 C, 13 C, 14 B, 15 C, 16 C, 17 B, 18 E, 19 C, 20 C,<br />21 78, 22 76, 23 30, 24 13, 25 12, 26 12, 27 2, 28 8, 29 44, 30 7.<br /><br />Overall, the document is a concise answer key with explanations showing how each result was obtained.
