From Derek Huby:
Get counting with First Count! This fun and engaging app is expertly designed to provide structured support in counting collections of up to 10 objects. The objects to be counted are arranged in a grid, helping young learners to recognise number patterns and distinguish odd and even numbers. Game play is simple; just set a target number, then touch the on-screen buttons to count objects until you reach your target. There are no penalties for mistakes! With a variety of bright graphics and plenty of sound and movement, theres lots for adults and children to talk about. For more counting games, upgrade to Go Count!, which includes two further activities - Fireworks and Number Maze.
