David's teacher is a believer in the importance of the colonial era in American history, which is good. She even got to go to Virginia on some sort of teachers' trip, where she visited Williamsburg and Jamestown.
At the end of the colonial section, the teacher had the students give individual presentations related to colonial history. One option was to impersonate a colonial American. So David impersonated Isaac Wall, my great-great-great-great-great-great grandfather (and thus David's great-great-great-great-great-great-great grandfather) who lived in Virginia in the early 1700s. David wore a period costume, discussed agricultural techniques of the era with the aid of a plowshare and sickle, and pointed out that Isaac Wall was the ancestor of contemporary 5th-grader David Wall. My wife, who attended, said David did well on his presentation, and I was glad to hear that.
