World Map Challenge! Edu Ed. vs Napier's Bones Simulation

Challenge your knowledge of world geography with World Map Challenge! Learn the locations of nearly 200 countries around the globe! This is the Education Edition of the popular "World Map Challenge! Geography" app. All content is fully unlocked with paid purchase of this app. Note: Education Edition does not include Game Center support, and there is not currently an Apple TV version. Features: • Fully interactive map (zoom, pan, and tap on the map to select your answer) with sound effects • "Continental Challenge" mode: Tracks your progress and earns you stars if you score high enough! • "Time Trial" mode: How fast can you tap 20 countries in order? • Multiplayer: Challenge a classmate to a head-to-head match over a local connection (Wifi or Bluetooth)! • Practice mode that allows you to study specific areas of a continent to help improve your knowledge. • Practice mode features an answer key that you can toggle on and off • Support for Apple’s Schoolwork app and Shared iPad deployments in the classroom. Assign "Challenge" regions to students, and track class progress! • Incorrect answers will cause the map to zoom to the correct location (not available on iPhone 4 and 4S) Credits: • Announcer: Shawshank73 http://www.freesound.org/people/shawshank73/ • Menu "ping": Bertrof https://www.freesound.org/people/Bertrof/sounds/131658/ • Colored world map (main menu): Otsego http://en.wikipedia.org/wiki/File:BlankMap-World-Continents-Coloured.png • Mapping class: stkim1 http://stkim1.github.io/MTImageMapView/

John Napier's contribution to mathematics was truly significant. Born in Scotland, Napier studied as a mathematician, physicist and astronomer. He is best known as the inventor of logarithms, but he also invented one of the first computing devices. The device, known as Napier's Bones, is manually operated and can be used to find the products and quotients of numbers. Napier's device was based on Arab mathematics and used the lattice method of multiplication. Each of the rods are inscribed with the multiplication tables for a specific number. By arranging the rods on the board, the product of two numbers can be found by performing addition operations. Use the Napier's Bones app to learn how one of the earliest calculating devices worked. More than 400 years ago, people used Napier's Bones to find the product of large numbers. In using this simulation you will discover a new way to multiply. Have fun!
