Make play groups, get a bunch of kids together and start games with them. Just be close by to make sure no injuries occur. Neighbours could come together and each take one day a week to encourage the children in your neighbourhood to play together. Each parent could take a turn on the different days of the week, before long you will have very busy kids, not to mention free time for the separate parents, whose turn it is not.

Have kids go out and pick different leaves up to put in wax paper is a great way to get them outside and walking around. The children adore little art projects such as this.

Go to the local park as a family and use the resources around you such as the climbing frames & swings. This is a great way of introducing kids into being more active without them even noticing the health benefits of strengthen their muscles & bones, as well as coordinating their body.
