- Read one note at a time and add the question, Like or Unlike What? 
 - You will usually think of no comparison, but when you do think of a like/different comparison, mark a large X on the notecard, after Like or Unlike What?
 - After you mark a large X on a note, set that card aside. 
 - Make a stack of all your cards that have a large X after Like or Unlike What?.
 - In the next step you will choose a few like/unlike comparisons, and you will write them on your note cards.
 - Your likenesses / differences: • must make sense    • must be true    • must not be silly.
