#### One Is a Snail, Ten is a Crab

by April Pulley Sayre & Jeff Sayre
illustrated by Randy Cecil

This very cute counting book that's based on the simple but clever premise of counting the number of feet different animals have, alone or together. Starting with a snail (1 foot), the text moves to a boy (2 feet), a boy and a snail (3 feet), a dog (4 feet)... Then, after 10, the numbers move up in increments of 10 (to 100).

This book was written specifically to teach math (but is super cute nonetheless!)  It would be a great teaching resource for the following math topics:

• counting -- loaded with opportunities to count (and even skip counting!)
• +1 addition -- the first half is single digit numbers plus 1 (the snail)
• +10 addition -- the second half is different 2 digit numbers plus 10 (the crab)
• multiplication -- lots of "real world" applications of multiplication!  We recommend you have the kids count the legs in a given spread, then use multiplication on the same spread. They kids will definitely see how much faster multiplication is!

We agree with School Library Journal, who ended their review by saying "whether with those just beginning to count or children starting to multiply, this original and clever book will have wide appeal."  We LOVE this book -- Get it!  :)

The publisher states that this book is for Preschool - 2nd grade, but we've bumped it up to 3rd grade (since that's generally when multiplication is generally introduced, at least in most American math curriculum.)

Below are sample pages from inside this adorable book.  We love the pictures!

Simple addition (+1): Here's an example of a page that shows simple addition (four legs on the dog + 1 leg on a snail = five legs)

: Here's an example of one of the spreads that is great for teaching + 10 (since each crab has ten appendages):

Multiplication
: Here's an example of one of the spreads that can be used to teach the benefits of multiplication (and of course, the above spread can as well):
