We rented this from our local library and now I want a copy! This video is really 3-in-one.1. Road Construction Ahead2. House Construction Ahead3. Farm Country AheadChock full of big machines, this video is mostly visual with background music and some explanatory commentary, my two-year-old loves it. The Road Construction shows how roads are built showing front loaders, excavators, dump trucks, graders, rollers, line painters, rock crushers, asphalt mixers, the works! The House Construction shows how houses are built and where the materials come from, including how concrete is made at the concrete plant and how trees are harvested and milled. The Farm Country shows where our food comes from and how it gets from the farm to the container you buy in the grocery store. Check out littlehardhats.comI might have learned more than my son!
