What are you aiming to do?
For the task:
Every member of the team has to end up with a set of four cards in
front of them that are related to each other in a similar way.
The task is only successfully completed when everyone on the team
has completed their set.
As a team:
- Responding to the needs of others
- Helping others to do things for themselves.
You will need to work in
a team of four. If you have a fifth person available - use them as
an observer (see guidance below).
Distribute the 16
randomly amongst the team (four cards each).

just pass a piece on without looking at what the other person or
team actually needs).
