I came across an alternative interpretation of how the Yupana works [1]. And I also came up with my own interpretation, since there is much information captured in the format that seems to be ignored by the other interpretations I have been able to find. So Version 3 [2] of the program supports the simple base-10 system recommend by [3], the base-20 system of [1] and my own, based on prime factors (1, 2, 3, and 5).
I will work on a version where the learner can create and explore their own interpretation for Version 4. regards. -walter -- Walter Bender Sugar Labs http://www.sugarlabs.org [1] http://www.atlantisbolivia.org/decodingquipumaths.htm [2] http://activities.sugarlabs.org/en-US/sugar/addon/4533 [3] http://cursa.ihmc.us/rid=1J2NH8QTM-2912G6-PZ5/yupana_como_herramienta_pedagogica.pdf _______________________________________________ Lista olpc-Sur [email protected] http://lists.laptop.org/listinfo/olpc-sur
