Getting some readings together

I want my students to read some things about Ancient Greek democracy and not just watch them, so I'm compiling a list:

There's one specifically for kids: http://greece.mrdonn.org/athensdemocracy.html
And a BBC link: http://www.bbc.co.uk/history/ancient/greeks/greekdemocracy_01.shtml
And here's another reading for kids: http://www.ducksters.com/history/ancient_greek_government.php

http://www.ahistoryofgreece.com/athens-democracy.htm

http://www.nelson.com/albertasocialstudies/productinfo/gr6_9/docs/abss6ch3.pdf has some interesting things related to a textbook, not for my students but maybe for me.

I'm thinking that I'd have my students read these in groups and then jigsaw the information they get from each reading to the rest of the class.
