Tiffini,
This is an interesting question. As we were designing the suggested grading, we did place a blank line next to the areas that we felt could be graded fairly easily. For me, things like oral narration are harder to grade. So, for those we placed '"goals" for the oral narration in parentheses next to each type of narration but no grading lines for each narration.
There are many possible ways to track whether your child has met those "goals." In my mind, I was thinking that I would just look for those goals as I listen to the oral narration, and if the student wasn't attaining the goals I would remind him of what we're trying to accomplish after the narration so the next time we could work better toward meeting the goals. I see narration as a process, ever improving, and if I'm too strict the flow of the narration could be lost.

With this in mind, giving a weekly grade in oral narration would discourage the process and flow. Instead, I'm thinking of a completion grade for narration each quarter or semester, unless the child is not putting forth effort. Then, the grade should reflect the lack of effort.
I would say that I look at the skills in the Expedition Journal the same way as oral narration, with the exception of the written narrations each week. The Expedition Journal provides a great record of work, and I plan to check it daily and make suggestions or give guidance if my student is not performing to the expected level required. This will ensure that the level of work is up to the standard I expect (without it sliding over time) and that the skills listed in the grading section are being met. With the daily checks, I think it would be easy to look back over the Expedition Journal entries at the end of 9 weeks and give an overall grade for those skill areas related to the journal. So, I'm thinking more of a quarterly grade there for my son that takes into account all those skill areas meshed together into a single grade. However that would be coupled with daily feedback on what he is doing well in those areas and what could be better. This is just my thinking though, and there are many other ways that the skills in the Expedition Journal could be graded.
Blessings,
Carrie
