Charlene,
When we were originally planning for Preparing Hearts, we were planning on a total format change for the future guides. There were to be Teacher pages and Student pages separate from one another. However, when visiting with HOD users on the board and at conventions, we found that they preferred to stay with the format of each day of plans on a two-page spread to make for less flipping between Teacher and Student pages (and less piecing together to see what needed to be accomplished each day). Users also preferred to have the "Learning Through History" on the left side of the plans and the "Learning the Basics" on the right side, remaining with the format we already had in place.
With our previously planned format change, we had planned to have the subjects instead grouped by Teacher Directed, Semi-Independent, and Independent allowing us to have the Student pages for independent work separate.

When staying with the current two-page spread instead, it was no longer workable to have separate student pages anymore and still stay with the one day on each two-page spread.
For the newest ancient's guide, at this time we are planning to have Student Notebook pages for history. This will be a place to record and insert all history-related assignments completed with Hearts for Him Through Time: Creation to Christ. The student will still need to read the plans from the guide, however.
I agree that our boys are carting the guide all over the house too, and have it with them at all times.

However, I've come to look at the guide as their set of plans (more than mine) for the day all written out for them, which saves me time that I spent in the past writing out schedules and directions.
With my older son, we've had to write out a schedule yearly and direction sheets for him to cart around in a 3-ring binder (since he's older than each of our completed guides). Then, whenever we meet, he's had to get out a different guide for me to teach from. So, either way my kiddos end up carting something around (and so do I).
I've been surprised that I've liked remaining with the guide's two-page spread a day format (as I was pretty set on a format change last year). I find it's very easy to see what my kiddos have accomplished and what they have left to do, when glancing over the day's plans. It's also easy to prove what we did each day and to see where we are in each subject area.
It's so difficult to decide on a format, and I know everyone will have a different opinion on what is their favorite format for the guides. We're just grateful at this point to have settled on the format we currently have in place, and we've made sure to publish the guides with a strong, lay-flat binding ready to take the abuse of a guide that can be hauled everywhere!
Blessings,
Carrie
