This engaging call-and-response book, a companion to OLLIE'S SCHOOL DAY, challenges readers to help Ollie prepare for a field trip to the aquarium. It's Ollie's first class trip! Where will his class go? To the moon? NO! Up into a bluebird's nest? NO! To a rainbow they can use as a slide? NO! Will Ollie's class go to the aquarium? YES! Before Ollie goes on the trip he needs help answering some questions, so he's calling on a trusted friend . . . the reader! Children will love being Ollie's helper as they answer his questions—some silly, some serious—while following his class through an exciting, fact-filled day at the always fascinating, fish-filled aquarium.
