In this biography worksheet, children read about Ada Lovelace, whose ideas are still used in computing today. Students learn how Lovelace, who was born in 1815 to Romantic poet Lord Byron, was encouraged by her parents to study math. Through a chance encounter, she met a mathematician who took her under his wing; her ideas later helped to expand upon and create what is today considered the first computer program. After reading a short biography, children complete a timeline and a graphic organizer to reflect on what they have learned. The Historical Hero: Ada Lovelace worksheet, designed for a third and fourth-grade literacy curriculum, helps support students' comprehension of key ideas and details in nonfiction.
