This document provides instructions for playing a homemade PowerPoint game called BattleGraph. The game involves students graphing points on coordinate planes to hide and locate virtual battleships. Students work in pairs, with each student hiding battleships on a hidden board and taking turns attacking points on their partner's visible board. The goal is to be the first to sink all of the opponent's battleships. The document explains how to set up the game, rules for gameplay, and examples of completed game boards.
