'The Solid' printed from http://nrich.maths.org/
is one of a series of problems designed to develop learners' team
working skills. Other tasks in the series can be found by going to
What are you aiming to
For the task:
The team has to make the solid described by sharing the information
on their cards and without showing each team member's information
to anyone else.
As a team:
- Allowing everyone to contribute
- Asking questions and finding out what others think
- Sharing knowledge and reasoning
- Reflecting and making use of what has been said
- Coming to a consensus
You will be working in a
team of four. Ensure that you have plenty of cubes. Their colour
does not matter but it may be less distracting to have all the
cubes of the same colour. You cannot use paper or pencil to help
you because you need to listen to what others have to say.
Discuss how you will work
together and share your ideas.
Put the 4 cards
face down in the centre of the table.
Tackling the problem
Each member of the team takes a card from the pile in turn (one
card each) without the others seeing it.
If you have an
observer, they might find the following list of things to look for
helpful and feed back to the team at the end of the task.
- Team members cannot show their cards to anyone else on the
- A team member can describe what is on their card.
- Team members can ask questions to help them make sense of what
is on their card, or on someone else's card.
- The task is complete when everyone agrees that the solid they
have made matches everything that is on their cards.
- Check that no one reveals their card or writes anything
- Identify points where team members share knowledge and
reasoning and listen to each other.
- Identify points where team members make decisions
- Note whether all members of the team are involved.
