These Beechwood stacking blocks feature illustrations that show the 5 life cycle stages of 4 different animals and insects: moth, butterfly, chicken and frog. All stages are labeled to assist with understanding of animal development. The stages are also ordered by the relative size of each block. The earliest stage is represented by the smallest block while the adult stage is represented by the largest block. This resource is a great tool for early literacy and science. Hand-eye coordination is developed as children grasp the blocks and stack them. The brightly colored illustrations are printed using heat transfer technology and coated with a non-toxic, matte varnish for durability. Sizes: 2.3"W - 1.2"W. For ages 12m+.
