Every now and again, we like to come up with something that isn't necessarily related to K-12 education. Several of us are interested in genealogy (family ancestry, or the family tree).
If you are actively trying to trace your family tree, or have ever tried, chances are that somewhere along the line you met (online or in person) a "cousin" who was/is doing the same thing. You know that you are related, and vaguely refer to yourselves as "cousins," but might not be precisely certain just how the two of you are related. We created a "cousins" family tree chart template that you can print or download for free here.
This chart works for two people with the same grandparents, great-grandparents, great-great-grandparents, great-great-great-grandparents, or great-great-great-great-grandparents. It comes with complete instructions for those of you who aren't the best at filling out charts like this.
The "cousins" (up to fifth-cousins, technically) chart is a real lifesaver when it comes to explaining how you are related to someone. Try printing up a dozen or so copies for your next family reunion. It might be fun to create one for (or let kids create one themselves) younger children to help them to understand family relationships. (It's educational, too, since all state and national academic tests require students to be able to create and read complicated charts.)
