Battle-shape

thingiverse

In this educational game, inspired by battleship, students compete in pairs to be the first to identify their opponents' shape coordinates on a graph. Each team uses separate boards to record guesses and hits/misses. To play, students place shapes on their board without stacking, then take turns guessing coordinates. After each attempt, opponents declare if it's a hit or miss and continue their turn. A shape is "hit" when all its points are guessed correctly. For advanced math classes, students can also guess lines using standard or slope-intercept form and mark them with rubber bands between pegs.
