Review

"Counting on Katherine" by Helaine Becker and illustrated by Dow Phumiruk is a must-buy for any children's biography collection. It is the perfect combination of a picture book with relatively simple sentences that still gets a lot of information to the reader. The repetitive phrase "count on me" is a great way to show how she used math to do important things (including sending Apollo 11 to the moon and getting the Apollo 13 astronauts back to Earth). The illustrations are lovely and detailed, but not overly busy. An excellent book for any library. ~Reviewed by Kate Radke

Overall Book Score: excellent
