In the summer, lots of families have more flexible time which you could use to do a treasure hunt style Bible exploration.
Produce a treasure hunt by choosing four to eight locations, depending on the age of your group and the time you have available. For each location write the next part of the text of a Bible story and a clue or simple directions on how to get to the next location. Make sure your story text and clues are age appropriate. To make it fun, use an unfamiliar Bible story such as Nehemiah or Hezekiah.
For children age seven and up, you could also have a letter to collect at each location which they then need to use to spell a key word when they have all the letters.
For primary aged children you could have clues such as:
Go to the tree nearest to the door.
Go to the lowest place in the building.
Go to the window in the smallest room.
For younger children use clues such as ‘under the big tree’, ‘at the top of the stairs’, ‘beside the door’ and use age-appropriate Bible text such as The Big Bible Storybook, and, if possible, have a picture for each part of the story.
You could try doing this together with another family with one family or one family member setting up the clues then everyone taking it in turns to find the next one.
