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.

Technical Remarks:

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

Technical Remarks:

el abaco no muestra el número ingresado completamente (solo las dos primeras cifras)
