Contact Steve Hinshelwood for further information about this technique.
I had about forty keywords written around the Apex walls.
Students in teams of four came up and were given another keyword. They had to link it to a word already on the wall (not if another group has got there first).
A second student from the group then reports the link back to me and gets a new word.
This worked well with a list of 20 additional words and produced some super links – I allowed some very tenuous links if it involved imaginative thinking.
First team to finish wins.
