This is a project that you can do with students when studying communities. We use this as a tool to build understanding of relativity and size (several cities can be found in a state because cities are smaller than states. etc).
We go through each one and students draw a picture of our school, state, city, country, continent, planet and then we cut them out and staple them all together.
**It's also helpful if you print them on different colored paper but this is not necessary!**
