Thousands of United States students will spend Monday celebrating the life and legacy of Dr. Seuss, née Theodor Geisel, as part of Read Across America Day 2015. The famous author is seen as a pioneer of children's literature -- between his birth on March 2, 1904 and death by oral cancer on Sept. 24, 1991, he wrote and illustrated 44 books.
In honor of his would-be 111th birthday, American youth, librarians and bookstores will revisit some of Dr. Seuss' greatest works. If you want to join them, don't get overwhelmed by the options. Here are the top five best-selling Dr. Seuss children's books on Amazon:
"Oh, the Places You'll Go!"
This book was the last Dr. Seuss work published before he died. It came out on Jan. 22, 1990, and follows a protagonist -- the reader -- as he explores a world outside his small town. Today, the book is a popular gift for graduating high school and college seniors. Here's the full text.
"Green Eggs and Ham"
Dr. Seuss used only 50 words in "Green Eggs and Ham" as part of a bet with his publisher, Bennett Cerf. The book came out in 1960 and encourages readers to try new things. In 2012, Scholastic Parent and Child magazine named it the No. 7 greatest children's book of all time. Here's the full text.
