We discussed this in Chat tonight and I promised to post a link.
This is a set of booklets suitable for use in a classroom. The first couple of books are rather general, but each subsequent book takes on a particular topic such as Jehovah's Witnesses, Mormone, Marian issues, etc. There are nine books in the set including a workbook for Book 1. Also included is a Bible Cheat Sheet which is a laminated sheet of some 500 scripture verses that deal with Catholic doctrine. Verses most often used against the Church are included also.
The books are available for $44.95 from Catholic Answers. They are more expensive than I said in the Chat because there are more books in the set now than when I bought them.
The books are available individually as well. They are also sold at my local Catholic store, so you may be able to find them locally.
