While I am incredibly thankful that God hasn't called me to be a CCD teacher this year (It is important to know where one's gifts do not lie), "Be an Amazing Catechist" by Lisa Mladinich looks like a great book for those of you who will be either returning to the CCD classroom or entering it for the first time. Lisa is a well-respected writer and columnist on CatholicMom.com. She also manages the Amazing Catechists website.
The official blurb is as follows:
Be an Amazing Catechist is a highly effective training program for the Catholic catechist. It is simple, engaging, and useful to catechists at every level of experience using any curriculum. You might not need every idea in this book, but you will find within it valuable tools for making your catechetical ministry more vibrant, more exciting, and more effective.
