End of the Year Math Project - Dodecahedron Dice

Write an original word problem for each of 12 math topics, including area, volume, fractions, and geometry.

Solve a peer-created problem for each of the 12 topics and record the work.

Assemble a 12-face dodecahedron net into a 3D shape by cutting, folding, and gluing.

Explain reasoning in writing for place-value and rounding problems, as the solo version requires.

Have students use a glue stick or tape to assemble the dodecahedron one piece at a time; the file notes students found tape easier and less messy than glue.

Choose the partner-exchange version to add a peer-review step, or the solo version if independent, self-contained work is preferred.

Display finished dodecahedrons by hanging them from the classroom or hallway ceiling once grading is complete.

Score the project with the included 4-category rubric rather than a single overall grade, since appearance, accuracy, completeness, and creativity are scored separately.

Cross-topic math problem writing — students compose an original problem for each of 12 distinct math topics, from area and volume to fractions and place value.

Peer problem-solving — in the partner version, students solve problems a classmate wrote and check their work against an answer/record sheet.

3D shape construction — students cut, fold, and glue a 12-face net into a physical dodecahedron.

Self-checking and explanation — the solo version requires students to show their work and, for place value and rounding, explain their answer.
