Directions:
Step One: Create a study note card for each stem
Step Two: Spend time each night reviewing your cards. (This can be done on the bus ride home, in the
car, or during study time in Inquiry class, etc.)
Step Three: Remember that the Word Within a Word is cumulative. That means once you have list # 2
you can’t just toss out list # 1. You’ll need to keep reviewing those words too! You’ll see them on Stem
Test # 2 and so on.
