Just a simple chart showing the different values of pencils. Those starting out pencil work should pick up a graphite kit that can be found at most arts and crafts stores. They're usually around 5-6 bucks. Also make sure you have nothing but pencils, some have charcoal and junk. Stuff you probably don't want to dive into right now.
If you can't find a store nearby, DickBlick.com is the way to go!
