Playtime for pre schoolers essential

I just read an article called playtime is essential for pre schools. The article was bout how young children should get more active and be able to go outside more in school. It talked about how allot children 2 through 19 are obese. In the article it says that most day cares and pre schools say that they don't worry about playtime because the parents are more concerned about the learning and academics then they are the activities. Researchers said that but by the kids getting time outside it also increases their brain development it does so by the child using skills that they use in the classroom in real solutions. I agree with the researchers i think that its a good idea for children for to get more active and have playtime. According to the article parents should be more interested in rather their kids are active in school. The articles said that children spend more time in the classroom then outside. Also, that playgrounds have to be up to date on the on their equipment, and that the equipment that they do have isn't as fun because kids aren't allowed to use them in the way they want because its not safe.
