The Questioneers series is a celebration of STEM, perseverance, and passion. Like its characters, Iggy Peck, Rosie Revere, and Ada Twist, every budding architect, engineer, scientist, mathematician, and leader, will become inspired to solve everyday mysteries and come to think more critically about their world. Most importantly, they will learn that despite inevitable difficulty in achieving success, they should always continue to “Read. Question. Think.”—and never give up on their dreams.

Picture Books

Written in irresistible rhyming text and illustrated in playful art, the Questioneers picture books are where it all began. Charming and witty, they introduce the students in Miss Greer’s second-grade class who are very curious, imaginative, and persistent—and determined to follow their passion in the field of STEM.

Project Books

Iggy, Rosie, and Ada take readers through a multitude of engaging STEM activities and projects—from drafting and doodling, building and blueprints to designing a better bicycle and constructing a solar oven. These project books teach problem-solving and creative-thinking skills while also providing opportunities for their readers to try new things and celebrate the inevitable flops along the way.

New readers can dive even deeper into the creative, inventive, and experimental worlds of Iggy, Rosie, and Ada.
