Blocks are one of the most valuable learning materials in our classrooms. When they build with blocks, children learn about sizes and shapes, spatial relationships, math concepts, and problem solving. When children lift, shove, stack and move blocks, they learn about weight and size. Generalizations about balance, sequence and gravity are made. When playing with blocks, children acquire many logical thinking skills, including the ability to make use of classification, seriation and equivalence. Each time they use blocks, they are expanding critical thinking by making decisions about how to build a structure or solve a construction problem.

         Blocks are open- ended play materials that allow children to create whatever they desire. There is no right or wrong way to build with blocks. Children can create whatever they want. Sometimes children start with an idea of what they want to make; at other times three-dimensional designs grow as children place blocks together randomly or in patterns. Like other art, the creations children produce with blocks are unique. Block play is an essential creative outlet for some children.
