Verse 4 says that it "was done that the word of the Lord might be fulfilled." What was the word of the Lord that was being fulfilled? Can you find the verses that mention it? How was His word being fulfilled?
Make family scripture time productive. Get the kids excited. If kids can see how the Book of Mormon applies to them and if reading the Book is FUN, you might hear, "Is it time to read yet?", rather than, "Do we have to?" We are counseled to SEARCH the scriptures, not just read them. It takes preparation to do that with children. This is the preparation that I've done. Now I have it for reference next time. And you do too. Comments welcome.
