We have been writing instructions for games with the Ruma ono hacky sacks. We started by creating a ruma ono game sensation called 'Think Fast', where we learnt that for writing instructions for games we need:
The title of our game
The goal of the game
The equipment required
Then how to play the game.
Below a link to a video of how we co-constructed our games. Our games need only a few rules simple easy to follow rules.
We then all went away and wrote our own games, which we taught to a teina class Room 3.
