Differences of today and back then would be really nice to point out. Milage by foot to school and then the milage on gas by bus. Gosh, I see all kinds of ways to impliment that story with different subjects in class. Another thing about elementary grades is that you all are still teaching all subjects.
Oh, and journals! You can even have them personalize their journals. Also, pictures are good to add to those journals. Have them cut out pics from books of that time era and then some from your class. Oh! And story book characters! Have them choose a character from the book and dress the part or have items that describe the character.
Boys can be hard to keep focused, so try the fishing they had back then compared to today. If you can keep fish in class, it's a great way to have them see nature. Have them draw fish, boats in water, etc. Have a local fisherman or Wildlife officer come in and talk to the class about the importants of wildlife in our environment.
I don't know where you live, but have senior citizens of the art crafts come in and talk about quilting, crocheting, tatting, woodworks, sugar cane making, etc.
Gosh, there are so many things that have ran through my mind and I don't have enough time to write it all down!
PS....I work in a school 6th -12th grades. No, I'm not a teacher, I'm the school registrar. I've been in the school system going on 18 yrs now. You have my whole hearted support. Good luck to you!!
