What you see here is a scan of the 2-page planner which I used 1997-98 for my two children. I liked stickers during that time. The stickers indicated a grade of 100 and my kids really liked getting a sticker when they made 100. We also maintained homemade sticker-books during that time as well.
The round things attached to the edges of the pages are make-shift dividers. The make-shift dividers are made from round sticker sandwich. They were placed at 6-week intervals.
Notice the line drawn partly down the middle of many of the squares. That divided the plans for my two children. The left side for my older child and the right side for my younger child (they were 3 grades apart.)
