Another thing we did in Sunday School when I was a child, was memorize bible verses. The one that I remember the most, and I believe is still one of my absolute favorites is John 3:16 (KJV)
For God so loved the world
that He gave His only begotten Son,
that whosoever believeth in Him should not perish,
but have everlasting life.
For God sent not His Son into the world to condemn the world;
but that the world through Him
might be saved.
