Thanks for thinking of me :o) Yes, we are enjoying RTR this year, but I can only comment on the Rome section so far, as we are just at the end of that -- about week 13 (dh is very ill this year).
Here are some random memories of things we enjoyed:
* A picture book of Roman numerals, as well as the Math-U-See lessons on Roman numerals if you can borrow those from a friend at all (I think they were at the end of Delta?)
* Dh and I enjoyed "preparing" for the year last summer by watching some of the recommended video series, such as Christianity's first 2,000 years, which wasn't too expensive (at Amazon or eBay I think).
* As others have mentioned, ds (age 11) LOVES the Drive-Thru history videos. (Thanks, Kelly & Crystal!) When we read about something like the Colisseum, ds will say, "Oh, that's in Drive-Thru, can I show you?" And as Lori mentioned, they are much cheaper at Library-and-Ed.
* We always enjoy getting one of the recommended art books each year, and looking at a Biblical painting every week or so, similar to Come Look With Me. Ds also enjoyed the suggested Art Fraud Detective.
* We have been doing the anatomy portion of science & ds loves his skeleton but he also enjoyed having some related hands-on kits for his free afternoons, such as growing germs from between his toes.
* Favorite books in book basket are body books with plastic overlays or actual plastic body parts (which I found at Sam's Club). This may be because we have had such a medical year at our house! But they are good gift ideas.
* My particular ds does not like all his reading to be about history. He has LOVED the read-alouds in RTR and he LOVES the actual Bible, but that is enough history for him. I think he is somewhat bothered by the failures of mankind, which are always easier to see in hindsight. So we do not use many of the historical fiction suggestions in book basket. Isn't it interesting how each family is different?
Edited to add more:
* We read The Apprentice during the weeks after Bronze Bow, when no read-aloud was scheduled. It didn't match the time period exactly, but, interestingly, it matched the art studies exactly! The RTR art project the day we started was on drawing a circle -- exactly what the boy had to do in the first chapter. The next RTR art project was on mixing paints -- exactly what the boy's job was in the next chapter! (God is in the details :o)
* I really loved reading a nice copy of Marguerite Makes a Book (as opposed to a wrecked-up library copy). It is a lovely book, with "gold" illumination and everything. I felt it brought to life all of the history and art lessons on illumination.
* During another year, my son read A Single Shard and really enjoyed it (early Korea), so I'd add that one for a boy who likes to read.
* I also would add Kingdom Tales to RTR, if you haven't read it already. The MFW version is far cheaper than the hardcovers, and MFW adds nice discussion questions at the end of each chapter.
