Choose an activity or two that will act as reminders of the story
If you have a large group, perhaps you could choose a messy activity, and a quiet activity for the different personality types. Older children often enjoy games and food more than crafts...but not always. Younger children can do complicated crafts, if a good amount of prep is done for them before the session. When taken home, good quality crafts that the kids are proud of can open up great faith conversations.
