Oh one more thing we did that was so much fun is we printed out small flags of the world ( one inch or so by two inches)  and pasted them onto popsicle   sticks (one flag per sick).  We organized the flags by continents.  So all the flags of Africa would go into one continent container.   To make this more fun we had printable maps and the children could match the stick to the correct country of the world 

   Just a fun way of learning for my kids 

   You can also do this project with all of the countries and that is what im working on making now ......
