# User:OLPC Mathematics

The revised XO Mathematics curriculum for January – March 2010 is ready. Week 1 starts on the 11th of January 2010 and the program will run continuously until the end of Week 12, on the 2nd of April 2010. The aim of this curriculum is to improve performance of Mathematics, and these are the areas we aim to improve by the end of the three month period. The XOs will simply be used to facilitate and make sure we teach these topics in a fun way and therefore stimulate the understanding faculties of these children.

Note that each row represents a week
