Grades

In the Classroom
This site would make for a great creative writing project for students in a high school english class. Have students search for their birth date, and find one person on that list that they can focus their paper on. Have students research their historical person, eventually writing a analytical paper about the similarities and differences between their own life and that of their selected person. Teachers can focus more on similarities to make it more difficult and interesting - but it is a great way to get students thinking about comparing and contrasting.Add your comments below (available only to members) | Become a Member
