My Grand children range n age from 9 to 17, and it was applicable for all ages. As my grand children and I went thru the book,  it was a fun, learning,  and bonding experience for us all.  It led to many good discussions and I was amazed how easily they were able to learn from the curriculum.  I even taught it to them in the car while we waited in line at the drive in window!  It made learning the Bible easy and fun,  and it tells the stories in Biblical  order,  which was extremely helpful to us all and made learning even easier. If you are considering this book,  I would whole heartedly recommend it.
