Work through the book of Proverbs with your CB and note all the verses that talk about finances. Categorize them, and discuss the implications of the verses.
There are several ways to do this--you could read each chapter together, or work on it separately. My Knight and I each took a half of the book and read a chapter a day for three weeks. Once a week we had a "quiet time" together to discuss the things we'd learned and compile our verses. How you choose to do the project depends on how you and your CB work best together.
