If you are using a full service curriculum provider (such as Seton Home Study), you no doubt have prepared lesson plans as well as forms for tracking grades and attendance.  If not, don't walk. . .RUN over to Donna Young's amazing site of free homeschooling forms and start printing!   

In addition to pages for tracking grades, I found that I needed a good daily log book to jot down what was actually accomplished each day as well as the minutes/hours spent on each subject.   In the past, I've used the Notgrass Record of the Lifestyle of Learning and I liked it ok.   However, the administrative assistant in me just couldn't leave well enough alone.  I wanted something similar, but needed to customize it for my family.  I kept a similar format, because I love how you can see in an instant which subjects haven't been completed yet today, before one day off from Latin becomes a week off from Latin!  So, in case it's helpful to others, here are photos and an explanation of what I created in a very short time in Works.   I create these pages one month at a time, which only means freshening up the weekly planner page four to five at a time.  Easy, easy.

On the right hand side each day is the log page.  I print off five of these for the week, and just put a fresh one on top each day.  This is where you can customize your log to reflect the materials you are using.  Boxes can be titled "Latina Christiana", "Apologia Physical Science", and so on.  Then you need only jot down which pages were completed, that a quiz was taken and the grade (if desired), etc.  It is so easy to quickly make a note of how much time was spent on that subject.  I have a bright red date stamper that I use on these pages, although in this example it looks like I had just written the date by hand.  I also stamp the date on completed workbook pages, quizzes, tests, and so on.
