This is the first page I have my students put in their journals for our unit on exponents. It's a great reference for them for those very simple rules like the zero rule, or when they forget what expanded form means.
There are two sets of notes per page, and the second page is two sets of the answer key. Be careful not to print the answer key for your students! (Unless you want them to just have all the info already written in for them.) Print just the first page, and only half of what you need, then cut papers in half to prepare for students ahead of time.
