"Impact of Debits and Credits on Account Types"
This page explains the rules of each of the account types in the accounting equation.
This page goes along with the "cheat sheet" which explains the accounting equation:

Students always love this. It's their "go to" the entire time during accounting.
They both go nicely in a plastic sleeve for students to reference
