Doorway Number Table is complete!

The next Doorway application is available. It's Doorway Number Table. The learner sees a number table. There are four sizes from 1-10 to 1-100.
Several numbers are taken away. The default is five but this can be varied. The learner has to replace the numbers - on counters, into the number. A very simple concept, but a very useful tool for teaching numbers up to 100 and their place in a number table. The way in which the user places the counters has been beautifully implemented in a method called "click to move". This makes Doorway Numbertable accessible to users with motor difficulties. It is also a delight to use this software using an intertacive whiteboard.
