I would suggest getting one of your kids’ grandparents, great uncles/aunts in to give the kids a talk about how it was. I just lost my last grandparent – a grandfather who was in WWII (actually both my grandfathers were). But he used to tell us stories of when he was in the war – not anything horrific, just some fun stuff they did. In case you don’t have anyone that can come talk to the class – which is sad because they’re so aged now and we’re losing some every day – here is on of his favorites that he like to tell:
They were in France camping near a chateau. They were very tired of eating their packaged meals (the WWII version of an MRE). They happened to be camped near a lake so my grandfather and a few other soldiers took some of their grenades, pulled the pin, threw them in the lake, and had fresh fish for supper.
You could also get your students to ask their grandparents who served to tell them their stories and present those to the class – one, this gets information to the students; but more importantly, it preserves the stories of these great and brave men and women.
