An important part of keeping Historical events straight for a student is a Book of Centuries. This is generally started in year 3 or 4 - before that either things are done with a family Book of Centuries, or else a Timeline or Timechart is used for the earlier years. (I think the timeline helps more with the continuity concept for the younger student.)
This is, of course, not a new concept. It is easily done with a page for every 50 years, causing a 100-year spread across the pages of a book. Many people will make the pages hold more years in the BC and earlier times, and hold less years in the later years - although I do wonder if that can cause confusion in the younger student.
I have also recently heard it suggested that for US (or Canadian) history, that a "Book of Decades" might be useful - because of the large number of things that occur in the last couple of centuries. I think this is a great idea.
Well, I had what I think is a great idea. I was thinking that we should make a "Book of Years" - actually a few of them. A 100 page book will give a beautiful space to put major events of each year of a person's life on a page. (even a 2 page spread). What a great way to learn about mom and dad during that portion of family history. And what a lovely way to keep track of each child's life - letting them pick out a few events to put in their book. I think this could create a treasured keepsake without a lot of work for "mom" as each child starts to take care of each of thier own "Book of Years".
