Fraction A Day - Day 14 - Numbaland

Check out Numbaland its Battleship Numbaline is a great program that reminds me a lot of the early Plato program Dart (Designed by Sharon Dugdale and David Kibbey 1975) as part of a program at the University of Illinois.  Plato was also used as part of the Madison Project.  It is discussed in chapter 3 of Cynthia Solomon's excellent book "Computer Environments for Children"
