Draw Perimeter is a measurement puzzle game that challenges players to calculate the perimeter of shapes and then grow a line to match that total distance. Across three game modes, students build their understanding of perimeter in increasingly complex ways. In Count Levels, players use a grid to count the spaces around a shape and determine its perimeter. In Puzzle Levels, side lengths are labeled, and players must add the lengths together to find the perimeter. In Puzzle Arcade, players encounter irregular shapes and use clues about congruent sides to deduce missing lengths before calculating the perimeter. The game strengthens K–5 mathematical skills including measurement, addition, geometry, spatial reasoning, and problem-solving. As students progress, they move from counting units to applying mathematical reasoning and analyzing geometric relationships to find unknown values.
