Preschoolers love to count. You can make your Bible lesson more fun and more interactive by letting them count just about anything they can - twelve disciples, five loaves and three small fish, five smooth stones, seven times that Naaman has to dip in the Jordan river, twelve sons of Jacob, ten lepers, you name it, they love to count it! If you have a visual with the objects on it, you can point and count, otherwise just go ahead and count up to the number of the object.
