Wouldn't it be great if the new schools being built now could finance something as imaginative as this .............

(and those being refubished !!!)
Skipping ropes, hoops, footballs .. are a few of the main playground activities (excluding any climbing frame/swing type equipment !!) that school & playgroup children used in my old haunt.
What activities do your children get up to in the playground .. Oh and 'It's dinner time Mr Wolf' lol that's a great game !!
