Sir Cumference and the Isle of Immeter a math adventure

Young Per sat with her uncle and aunt, Sir Cumference and Lady Di of Ameter. Her cousin Radius was teaching her the game of Inners and Edges.             "A player makes a shape out of tiles, calling out the number of squares used," explained Radius. "The first person to correctly count all the outside edges keeps those pieces."             Sir Cumference arranged his tiles into a square. "Inners are nine," he said.             "Twelve edges," counted Per, gathering up her winnings.
