Looking for something fun to add to your day? How about a short unit study as a break from those textbooks? The Old Schoolhouse is currently offering the whole set of Curiosity Files Unit studies free with the code, “Celebrate.” We used several of these when Emily was younger and she loved them. Where else can you spend a week learning about dung beetles, slime eels, quicksand, or zombie fire ants while practicing math, doing crafts, and learning vocabulary and science? This is usually a $125 set, so get it while this offer is still valid!
