The Large Group/Small Group format is for DELTA clubs with more than 15 kids. The DELTA Understanding God's Story Large Group Leader Planbook contains scripted Bible Explorations, Bible Memory review, prayer content and more.

Churches running DELTA in the Large Group/Small Group format will also need a Small Group planbook for each small group leader. The DELTA Understanding God's Story Hiker Small Group Planbook facilitates age-appropriate discussion of the Bible Exploration presented from the DELTA Understanding God's Story Large Group Leader Planbook. It focuses on the kid’s handbook Bible activities, application of the lesson, Bible memory and prayer content. The DELTA Understanding God's Story Hiker Small Group Planbook corresponds with the DELTA Understanding God's Story Hiker Handbook. The Hiker Small Group Planbook and Handbook are designed specifically for 1st-2nd graders, but can be adapted to include Kindergarteners as well.
