World Maps Online has a great collection of free lesson plans on how to read and use maps, for ages K-3, grades 4-5 and grade 6 and up. They offer their own classroom maps and globes for sale, and they are very good ones too — but honestly, you can probably use any detailed wall map of the US and world that you have handy for most of these step-by-step lessons, which can be read online or downloaded as PDF files. They are a great way to introduce geography to your students!
