Social studies lesson plans often need something to spice them up. One thing you can use with an Underground Railroad lesson plan is this National Geographic site. It can also help students learn some Underground Railroad routes.
When you enter the website, you begin your voyage on the Underground Railroad. You are told you are a slave in Maryland in the 1850s, and you can choose to escape to freedom or stay where you are. If you choose YES, then you begin your voyage. Sometimes, you have a choice, such as whether or not you should approach a house with a lantern, and sometimes, you just click to move on your way up north. If you continue to choose correctly, you will make it to safety and freedom in Canada.
Besides the fact that this part of the website is interactive, which most of your students will enjoy, it is also informative. Each time your students are taken to a new screen with a new choice, there are facts about the Underground Railroad. Your students will learn about Harriet Tubman, safe houses, Thomas Garrett, William Still, and crossing Lake Erie.
