This set of 9 pattern blocks can be twisted and turned to different patterns based on the guide provided (The set comes with a guide booklet). Start your child off with basic designs (4 blocks), then intermediate (6 blocks), and finally to advanced (9 blocks). Certain faces of the blocks can be configured to show the face of a blue teddy bear, and others can be arranged to show different tangram-like shapes. The blocks are easy and safe for tiny hands to grab, and the colors help children to recognize different shapes at an early age. Kids will always remember and cherish their first ever set of building blocks!
