CREATION - TWISTER
We have two life-sized boards that we made ourselves. One, for creation, is based on Twister, although with seven colours, each with a symbol related to a day in creation (we have used it for other topics with the colours representing different concepts).
GAME BOARD PATH
The second is a general path game, as described by others above. In both cases, we used old sheets and curtains sewn together and then painted them. This gives a less uniform look than canvas tarps, but is cheaper and more environmentally friendly. Any project like this is a huge investment in time, so putting some thought into the board design so that it can be used for multiple lessons is advisable.
