Book excerpt: At Penelope Pig's sleepover party, six pigs in pj's eat pizza and pasta, pound a pinata, pin the tail on the pony, prance to piano, and then form a precarious pyramid--collapsing, of course, into a sqealing pig pile! Maggie Smith combines rollicking rhymes and infectious alliterations to make a perfectly pleasing book filled with fun and the letter P. And while there are scads of P words in the text, the art has even more--the pictures are filled with more than 75 objects beginning with the letter P for young readers to find. The playful pictures also introduce other preschool concepts, such as colors, shapes, patterns, and counting. Pigs in Pajamas offers a fun way to get preschoolers thinking about language and building their vocabularies. Party on, Penelope Pig!
