Today, I'm posting a set of three free, printable activities I've found on various classroom blogs.
The first was found on ThirdGradeIsAHoot, where you can check out the class' state research project posters, and find a set of printable sheets so you can do the same activity with your own students. Scroll down from the (very neat) dioramas to see examples of her students' cool posters, which include a state flag,bird, flower, tree and map of the state alongside information they've researched. The printables at the very bottom include sheets to record their findings during the research process.
Assign each of the kids in your class a different state, mount the posters on construction paper, and use them for a nice display!
