One of the favorite "loose parts" in our playground are the bike tyres. Easy for the kids to pick up and move themselves - and, more excitingly - to roll along the ground and knock stuff over.
This led to the building of tyre ramps - designed to give the tyres more speed and knock stuff over in a more spectacular fashion.
At the beginning of the year the ramps were simple, beginning with the plastic slide:
Moving on to building ramps with wood and milk crates:
Until now as we zoom towards the end of the year. the ramps have become complex and complicated combinations of a whole array of different materials:
I love watching how giving the kids a playground full of loose materials - and the time and freedom to use them as they please - allows them to revisit and build on their past learning, experiences and discoveries and to make connections and deepen understanding.
What started out as a slide used as a ramp - over many months - becomes a collective construction of materials to build a tyre roller coaster.
Kids are pretty darn clever when we let them figure stuff out themselves, aren't they?
