The Big D is a Biblically based 12 week curriculum designed to be used in a group setting. It is best to be used in an hour and a half time frame but could easily be extended into 2 hours. The Leaders Guide gives you detailed step by step instructions on how to lead each week and lists all the supplies and preparation needed. Each participant should have their own Student Workbook which includes weekly worksheets to personalize their journey along with a section at the end of each chapter that encourages them to apply what they have learned to their personal situation, their family relationships and their relationship with God. There are also worksheets that can be sent home for the parents at the end of the Leaders Guide. The kit also contains an Activity Guide which is filled with over 138 pages of additional activities with a twist that specifically applies to their situations. There will also be a CD filled with video clips of other teenagers sharing about their experiences.
