We've used DITHOR many years now, and you are going to love it!

The minimal overlap that is planned is intended, and we found it actually helps younger ones retain the foundational concepts better earlier. Here's a rundown of the skills covered in BHFHG's Storytime box:
*Day 1: introduce and study different types of literature
*Day 2: model narration to foster comprehension
*Day 3: identify and analyze a different story element for each genre
*Day 4: relate personally to one Godly character trait, compare Biblical and book characters, and make a bookmark as a reminder of the trait
*Day 5: practice narration by retelling the story
Only Days 1, 3, and 4 relate to DITHOR, and as they are done after the parent has read the book aloud, they are more in a guiding/modeling sort of way than they are in DITHOR. In DITHOR, the child is responsible for the reading, as well as learning these skills and many, many more skills. For this reason, the slight overlap was wonderful, as I could "help" more with it during the Storytime sessions, and expect more from my child during the DITHOR sessions. On a sidenote, we tried doing the same genre in Storytime that we were doing in DITHOR, and we also tried doing different genres. It was fun both ways! We ended up preferring to do separate genres just to be reading different types of books, and also as it gave a natural review for the ones we'd done before in Storytime when they came up in DITHOR. HTH!
In Christ,
