Discussion for Abacus

Intersting site and getting more fluid in browsing sites. I was mainly interested in the history of the abacus and this site directed me in just what I wanted to find out.
Very easy to navigate to, and very simple to understand the history of the ancient mathmatical tool. This site shows how far in a very short ammount of time, as wellas, the appreciation of my calculator.
Time spent reviewing site: 15-20 minutes.

Demasiado simple, existen dos entradas para el mismo Objeto de Aprendizaje, el segundo Objeto de Aprendizaje no responde al link que tiene
el abaco no muestra el número ingresado completamente (solo las dos primeras cifras)
