Since the publication of this book in February 2017, I have streamlined the way I teach the “four moves” that are central to this book. While many instructors prefer the detailed approach to these skills laid out in this book, instructors (and students) may want to check out these more recent resources using the same methods that have been published since.

• The Check, Please! Starter Course presents the four moves with an updated acronym “SIFT”, and some more recent examples.
• The Ctrl-F Project by CIVIX is a short curriculum aimed at high-school students but suitable for early college students as well.

While these resources use the new acronym SIFT, the moves are essentially the same, and if desired can be integrated into the teaching of this book, or used on a stand-alone basis.
