Playing with blocks helps children develop in multiple areas. Block play allows children to co-construct and negotiate, increase their vocabularies, and improve math skills. It teaches them about science and math concepts, such as gravity, balance, and geometry. Building is all about size, shape, weight, leverage, and balance, and as your child works this out, their building and block play will become more and more complex. They take turns, share materials and cooperate with others, forging new friendships. It also encourages self-reliance, increases attention span and develops their sense of self.
