We already know that play is the way children learn and develop. Young children learn in an integrated way, meaning that when they're playing with blocks, they're also coming to grips with concepts like spatial integration, balance, shape and distance.
They learn to problem solve, they develop fine and gross motor skills, they develop cognitive concepts and social skills through learning to cooperate, negotiate and take turns.
Whether it's in a more structured environment like nursery school or simply some time on the carpet at home, playtime is invaluable for small children.
And if the advertising messages we're given are to be believed, there's nothing more integral to the educational value of playtime than the toys we buy for our kids.
