As longtime readers will know, I'm a big proponent of students studying their own communities. (You can read more about why and how in this post I wrote in 2012).
Architectural historian Carroll Van West's blog, "Revisiting Montana's Historic Landscape," is a great resource for local study--particularly if you are interested in learning more about how your community's history is reflected in the built environment and involving students in learning about heritage preservation.
To find articles on your community in this blog, type your town's name into the search bar (top right).
You can find more ideas for local study by scrolling through past Teaching Montana History posts about local history projects. There you'll find resources and models for researching local brands, partnering with your local museum, participating in crowd sourcing projects like HistoryPin and What Was There and much more.
