Treasure Map [Paperback]

Matthew has found a treasure map, and soon the Elm Street Kids' Club is off on a quest. The map guides them into a wonderful, magical world, but it's the real-life math skills of understanding distance, scale, direction, and symbols that will help Matthew, Sheri, Meg, Danny, and Jed -- with some assistance from Petey the parrot -- find a treasure hidden fifty years ago.
