This board book full of triangles and clever cut-outs is a wonderful way to introduce babies and toddlers to shapes.

Is it a house? A sailboat? A hat or a flag? Read aloud and create a clever guessing game about shapes that will delight and stimulate the youngest readers. Triangles are everywhere, and the shapes and colors found in everyday objects come to life when the pages of the book are turned. 

Learning shapes is a lot of fun when there are surprises involved—this die-cut board book from master artist and designer Yusuke Yonezu is full of them.
