As a measurement tool we used empty raisin boxes.
This helped the children to really look around and think "what can fit in this box?"
Once they filled their boxes we headed back to the school.
Inside we emptied the boxes at our Fairy table and started to play.
As the children collected their bits outside I overheard a couple of things they imagined they could be; like a stove or a blanket.
I'll be watching and listening for more of their ideas.
