Zero feels left out. The other numbers laugh, play, and build together—but never with him. They call him “a big fat zero,” and he begins to wonder if he’s worth anything at all.
So Zero sets out on a journey to discover his true value. Along the way, he helps a little girl count to ten, makes numbers grow bigger and stronger, and even stands up to the mischievous Divider, a villain who tries to split every number in two. But Divider has no power over Zero… because you can’t divide by zero!
✨ With playful rhymes, vibrant illustrations, and an inspiring message, Big Fat Zero helps children ages 4–8 learn about:
Counting, place value, and the magic of zero
Simple math concepts like tens, hundreds, and division
Confidence, self-worth, and belonging
Problem-solving and teamwork
Perfect for parents, teachers, and homeschoolers, this book blends STEM learning with a heartfelt story kids will love to read again and again. Whether at bedtime, in the classroom, or as part of a math lesson, Big Fat Zero shows that even “nothing” can become something truly special.
⭐ A must-have for fans of The Day the Crayons Quit, Zero by Kathryn Otoshi, and playful math stories that make learning fun.
Give your child the gift of confidence, courage, and a love for numbers with Big Fat Zero!
