I don't even need this info now, but I will for next year.

I had automatically planned on using the Extension Package with Bigger next year for my ds. I guess my confusion comes from a post where I believe I saw Carrie talking about the Extension Package and I thought she said the poster would not need it since her dd would still be 9. I thought it was said that the extension pack was for 10 and older. So my confusion comes from what I'm seeing on the website. It says it's for grades 4-5. Next year my ds will be in 4th grade, but he would have just turned 9 in June, basically 2 months before his 4th grade year and he won't turn ten until that year of school is over. Again all this is for next year and I hope I'm not confusing anyone.
My questions are:
1. Should I use the Extension Package or not with ds?
2. How long does it add to the day? If I remember I asked this before and it was about 15 min/day.
3. Can you please describe the activities that go along with these books? Narration, etc...
Seems like I had another question, but I can't remember right now.
