Let each of the other three persons in your small group sort your
cards into groups of cards. Record the results of the card sorting before
passing the cards to the next person. Here is an example card sorting result
with 9 cards:
Group A: 2, 5, 6, 7
Group B: 1, 3, 4
Group C: 8, 9
Each person that sorts the cards is free to decide how many
groups there are.
