A series of five photographs show the three most familiar geometric forms.

From the dream team of Jon Klassen and Mac Barnett comes the second instalment in the exciting new shape trilogy. Every day, Square brings a block out of his cave and pushes it up a steep hill. This is his work. When Circle floats by, she declares Square a genius, a sculptor! “This is a wonderful statue,” she says. “It looks just like you!” But now Circle wants a sculpture of her own, a circle! Will the genius manage to create one? Even accidentally?

Fall is here, with all its wonderful visual delights—not just colors, but shapes! This clever concept book follows a family on a trip to a pumpkin patch and invites children to pick out shapes from the seasonal scenery—apple bushel circles, square hay bales, diamond kites in the autumn sky! Felicia Sanzari Chernesky’s sweet verses are perfectly complemented by Susan Swan’s gorgeous collage-inspired art.

In the early 1960s Italian design legend Bruno Munari published his visual case studies on shapes: Circle, Square, and, a decade later, Triangle. Using examples from ancient Greece and Egypt, as well as works by Buckminster Fuller, Le Corbusier, and Alvar Aalto, Munari invests the three shapes with specific qualities: the circle relates to the divine, the square signifies safety and enclosure, and the triangle provides a key connective form for designers. One of the great designers of the twentieth century, Munari contributed to the fields of painting, sculpture, design, and photography while teaching throughout his seventy-year career. After World War II he began to focus on book design, creating children's books known for their simplicity and playfulness.

The three most basic shapes -- squares, triangles and circles -- are all around us, from the natural world to the one we've engineered. Full of fascinating facts about these shapes and their 3D counterparts, Shapes in Math, Science and Nature introduces young readers to the basics of geometry and reveals its applications at home, school and everywhere in between. Puzzles and activities add to the fun factor.

Multi-award-winning, New York Times best-selling duo Mac Barnett and Jon Klassen deliver the final wry and resonant tale about Triangle, Square, and Circle. This book is about Circle. This book is also about Circle’s friends, Triangle and Square. Also it is about a rule that Circle makes, and how she has to rescue Triangle when he breaks that rule. With their usual pitch-perfect pacing and subtle, sharp wit, Mac Barnett and Jon Klassen come full circle in the third and final chapter of their clever shapes trilogy.

Whenever you are -- inside or outside -- there are shapes to discover. And with Tana Hoban's help you will begin to see them. Look around. How many circles, squares, stars, triangles, hearts, and rectangles can you see? They are everywhere!
