We just finished studying Unit 24, of Tapestry of Grace. To go along with the battles between the Persians and the Greeks, we found JuniorGenerals.org. It has gobs of games to simulate historical battles throughout the centuries. We had a blast cutting, taping and creating the game. Thanks to Molly's Blogspot for introducing us to these soldiers. She also has a blog titled Historical Paper Soldiers. We used these soldiers and these triremes. Here were the directions to the game. .
The directions indicated to use a ruler to make your moves. This was perfect for my dear children ages 8, 10 and 12.
Check out this great game board they made out of large drawing paper.
