Hour of the Olympics and Ancient Greece and the Olympics by Mary Pope Osbourne and Natalie Pope Boyce
Both of my kids LOVED the Magic Tree House series which we call “the Jack and Annie books” in our house. If you have not discovered this awesome series it involves Jack and Annie who are brother and sister and they have a magic tree house near their house that takes them on adventures to different time periods. What I love about these books is that Jack and Annie’s adventures always begin with a book they have in their tree house and that with each adventure the reader learns a little piece of history. Our kids love the stories and the suspense and are learning all at the same time. LOVE it!
The Magic Tree House series has two books that focus on the Olympics. One is Hour of the Olympics which is about Jack and Annie’s adventures in Ancient Greece during the first Olympics. The second is Ancient Greece and the Olympics which is a non-fiction companion book to Hour of the Olympics.
These books are so fantastically well written and so much fun. I will warn you though, once your kiddo gets started on the Jack and Annie series it’s going to be a while before they read much of anything else. 🙂 There are a lot of these books and they are all fantastic and kids just eat them up.
