Use this storybook guide with the book “One is a Snail, Ten is a Crab.” Many public libraries have this book.
About the Story
Each page of this book invites children to count the number of feet people and different animals have. Children will enjoy counting from one to 100 with silly snails, insects, dogs, and crabs. One important caution: The story talks about the number of animals, but the math is really about the number of feet on each animal. You may need to clarify this (potentially) confusing usage.

About the Math
This is a book about counting. In this story, children can learn:
- The last number of feet we count tells us the total number of feet on the page.
- When we add one foot of a snail, we add one more to the total number of feet on the page.
- How to count by groups of 10 using a crab’s 10 feet.
- How to add smaller numbers of feet to make bigger numbers.
