I was researching some information about using blocks with children. I am always impressed by how many skills are reinforced through the use of blocks. Spatial sense, classification, patterning, shapes, cooperation, and planning are just a few of the experiences that children can have with blocks. I am also impressed by how important it is to leave block activities somewhat open-ended. Open creative thinking allows blocks to be a useful tool even an children get older. The kindergarten child creates different things with the same blocks he used as a toddler. It is important to have a variety of blocks available for children. They are also one of the most cost-effective tools and toys a parent or teacher can purchase.
