Students work in teams of five or six, each assumes a role as found in the construction industry. They have to replicate a model made of coloured blocks. Only certain members of the team can see the model. The only person allowed to touch the blocks does not see the model. The activity is about communication, teamwork and time management.
The activity is about communication, teamwork, presentational skills and time management.
Tactics are brought into it as the team have to assess whether to lose points for extra visits to see the model, to reduce mistakes on their replica.
It sounds a little trivial and dry from this description, but I make it very fast moving and put the students under pressure!
