I just took like 15 scriptures on fasting and prayer and wrote down the book and verse it was found on a strip of paper. I hid them all over the house. I did put it on bright green paper so it was easier to spot.
My kids love to read on their own from the scriptures so they had incentive to find as many as they could because then they could read that many.
It was a great fun way to teach and they really liked it. So I thought I'd share. Actually Katie told me to share :) heehee
