Building a replica of the Parthenon and the Theater of Dionysus of the Acropolis was time consuming and not something I would schedule again any time soon; however, it would not have been possible without Ancient Greek Monuments by Steven Savage. This book comes with a printed model of the Acropolis and Parthenon that you cut, color, fold and glue together. The paper is thick high quality paper. All you need are scissors, glue and color pencils, but an X-acto knife and metal ruler really help with the details and hard to reach places.
This project was scheduled for one week for our homeschool Ancient Greece unit, but ended up stretching over three weeks. My 11-year-old did the project in stages, and did a lot of the cutting and folding while I read to him for his lessons.
