In the timeline workbook are a series of outline world maps. There is a system of referring to these maps throughout the timeline. The student makes up his or her own numbering guide based on locations that they come to in their studies.

As an example - suppose the student studies an event that happens in Jamestown and it is the first time they are entering information into this timeline. Jamestown would be their No. 1 location. They would enter a very small "1" where Jamestown is on the map and then they would make a small key on the bottom of the page and write 1 - Jamestown. In the example No. 2 is Boston and No. 3 is Washington D.C. They are encouraged to not write "Jamestown" on the map because it would quickly become filled with names and soon become almost useless.

Now whenever in the timeline there could be a focus on Jamestown, a small 12-1 is written in the timeline. The number means 12 for Map No. 12 and location No. 1. For instance when putting Captain John Smith in the timeline, he lived first in England so by his name could be 4-1 because Europe is Map No. 4 and Willoughby, England (for example purposes) was the first notation on the page - Willoughby is known throughout this sample as 4-1. Then when he came to the New World, he was in Jamestown. See the examples of the timeline pages with his pictures. The first is by the date when he was born and the second during his time in Jamestown.
