Engage mathematical minds with the Guinness World Records Officially Amazing 2014 edition. This book’s “augmented reality” allows readers to virtually meet record holders. Download the free app to see 3D animations, videos, and other interactive features. (In the image below, I’m getting a little too close to the largest carnivorous dinosaur.)
The book creates a spirit of inquiry and is a fun resource for developing math problems, strategies, and wacky ideas.
