NASA also has this resource for teaching about extrasolar planets. Students will create an exoplanet in this learning activity.
Dr. Wladimir Lyra argues that exoplanets should have names too. Investigate his claim and perhaps have your class come up with names for future planets.
Exoplanet Lesson Plans

Undiscovered Worlds - a great resource for teachers - it is actually a guide to a program at the Museum of Science in Boston, but has great potential for the classroom.
Build a scale model of our Solar System with NASA.
If you have access to a scrollable screen, see this scale model of our solar system. Lots and lots and lots of scrolling required — which may work better with the right-arrow key rather than the mouse — but so worth it.
Compare the planets' sizes in our solar system — all in one image; no scrolling required!
