Through pbs.org, this is a great page to find classroom resources when teaching students about Lewis and Clark and their expedition. What I find most interesting, and what I think would be most useful to teachers from this page, is the lesson plans that are included. There are several lesson plans on this page, and the lessons are categorized by social studies, math, science, and language arts. Who knew you could incorporate lessons about Lewis and Clark in all subject areas? Some of the lessons may be for higher grades and may not be on grade level standards for elementary grades, but they can be tweaked to fit in your classroom for your students!
