Counting on Katherine

Helaine Becker

Katherine Johnson was an African-American mathematician who worked for NASA during the space race (you may know her from the movie or book Hidden Figures). This picture book follows Katherine from a young child who loved counting, to being a gifted student, to bringing her talents to NASA, and at every step repeating, “You can count on me.” She not only calculated the course of the moon landings, but also saved lives making sure that Apollo 13 returned home safely. The book also does a wonderful job explaining in simple terms both how and why math was so helpful in sending a rocket into space.
