Get out and play!
I can think of no other time of the day that elicits as much excitement and joy as playground time. We cannot open the gates fast enough to let the children into this area of possibilities.
The benefits of outdoor play are substantial! The obvious one is the opportunity for physical development, but all of our developmental domains are supported through outdoor play. Children run, climb, jump, roll, build, dig, wrestle (when appropriate), play games (interaction and cooperation), kick balls, shoot hoops, collect stuff, ride tricycles, pull wagons, roll wheelbarrows, take walks, talk with friends (communication), find a secluded place to rest (self-esteem and independence), crawl through tunnels, color with chalk on the sidewalk (artistic expression and appreciation), observe bugs, birds and squirrels (discovery and exploration), fill feeders, and the list can go on and on.
The playground is also a place where children can challenge and realize their capabilities. It's a place where they might get hurt and have to work through it. It's a place where they can comfort those who get a scrape. It's a place where games are created, adapted and played for weeks on end. It's a place where children can connect with nature by watching an ant, planting flowers, laying in the grass, drawing a tree or listening to bird song.
Well... why are you still reading? Go outside!
