Perimeter – Find Missing Total is an interactive, classroom-ready math game that helps students practice perimeter by solving missing length and missing total problems. Players use the equation Total Perimeter − Sum of Known Sides = Missing Length to find unknown values on shapes and real-world scenarios.

This multiplayer perimeter game supports 2–4 players, making it perfect for math centers, small groups, review days, and intervention. Each round includes a clear visual model (not to scale), focused input boxes for showing work, and a built-in work pad for drawing, labeling, and calculating. Students earn points for correct answers, and the timed format keeps engagement high.

To add even more excitement, correct answers unlock a quick bonus mini-game where students click the correct multiplication or division fact for extra points—reinforcing fluency while staying connected to the main math goal. The game also includes optional text-to-speech to read questions aloud, which supports accessibility and struggling readers.
