In a recent meeting with a new homeschooler I discussed teaching classes concurrently. I discussed that how science, history, and language arts can be aligned to make homeschooling more cohesive. Religion, for example, can be taught at the same time as history following the same time line to teach from the bible and to also teach events that have affected religion through the ages.
I considered created my own time line, but there are so many neat websites already compiled, that it would be better to introduce you to the best one available.
If you are looking for history back to when God created the earth (which is hard to find) this website has an Old Testament History Time line beginning with Adam and Even and continuing through 445 BC, before the birth of Christ. The sister site, continues from there beginning with the reign of Herod I and ending with Revelations.
Konig.org has a religion history time line that focuses on the old testament. It begins at 2100 BC with Abraham, and ends with the completion of the bible during first century AD.
The Christianity in View website has a Time line of Christian History has a time line that covers events from the calling of Abraham through the death of Pope John Paul. The website also has an African-American Church Time line.
Christiantimelines.com has a series of time lines that you can follow. They are separated by century. It goes from First Century which begins with the Birth of Christ and ends with the Fifth Century ending with Pope Felix III and the baptism of King Clovis of France.
The Christian History Time line website gives a glimpse of history and life before Christ, but really starts at the year 1 BC. This website is best used by following the time line along side your history time line, inserting stories and instances from the Bible as they occurred between the historic events.
To make teaching religion and history together easier, I like to take my favorite textbook and write on the table of contents page, inserting important religious information to cover as we progress through the book.
