Sayre, April Pulley: One Is a Snail, Ten Is a Crab: A Counting by Feet Book

"The buggy-eyed insects, crabs, and snails provide an appealing cast of characters who stand up to be counted against a summertime palette of orange sand and blue skies." — Kirkus Reviews

If one is a snail and two is a person, we must be counting by feet! Just follow the sign to the beach, where a bunch of fun-loving crabs, lounging dogs, gleeful insects, and bewildered-looking snails obligingly offer their feet for counting in a number of silly, surprising combinations — from one to one hundred!Seeing patterns and different ways of calculation are standard concepts of mathematical reasoning, but there is nothing standard about this creative counting book . . . The buggy-eyed insects, crabs, and snails provide an appealing cast of characters who stand up to be counted against a summertime palette of orange sand and blue skies.

This husband-and-wife team (HUMMINGBIRDS: THE SUN CATCHERS) puts a beach community's best feet forward and simultaneously explores the myriad ways that numbers can combine.
—Publishers Weekly

Quite simply, this provides little arithmeticians with something they'll actually get a kick out of counting. . . . All groupings are arranged for easy enumeration by kids not quite ready to make the leap to intuitive multiplication.
