Sally's family doesn't believe her when she says there's a hippo in the yard--but that's not the only surprise in this Level F book for emerging readers. "I don't think so, dear," says her mom. So Sally just takes some lettuce to feed the hungry hippo. Dad doesn't believe her about the tiger, and Nana won't put down her knitting to go see the koalas in the hammock. Lively illustrations by The New Yorker cartoonist Liza Donnelly capture the hilarity of a garage full of zebras--and the satisfying shock on everyone's face when it turns out the zoo animals have escaped. and Sally knows just where to find them! The award-winning I Like to Read(R) series focuses on guided reading levels A through G, based upon Fountas and Pinnell standards. Acclaimed author-illustrators--including winners of Caldecott, Theodor Seuss Geisel, and Coretta Scott King honors--create original, high quality illustrations that support comprehension of simple text and are fun for kids to read with parents, teachers, or on their own! For kids who've mastered the earlier levels, Level F readers feature longer, more varied sentences, and encourage kids to decode new multi-syllable words in addition to recognizing sight words. Stories are more complex, and the illustrations provide support and additional detail.
