Cube NetsTask 31 ... Years 2 - 10SummaryA net of a cube is defined and students are asked to find the 11 different nets which can fold up to make a cube.
This cameo has a From The Classroom section which includes photos of the students' gallery of solutions and slideshows from two students showing how they can fold particular nets into cubes. |

IcebergA task is the tip of a learning iceberg. There is always more to a task than is recorded on the card. |
Generally students begin with a Guess and Check strategy, but as the data builds up (and hopefully is recorded as a set of drawings) guidelines start to emerge.
When the students have found and recorded all 11 (perhaps in a way which shows the 'longest line families'), there are still several possible investigations.

Whole Class InvestigationTasks are an invitation for two students to work like a mathematician. Tasks can also be modified to become whole class investigations which model how a mathematician works. |
The only way to satisfactorily turn this task into a whole class lesson is to have sufficient 3d Geoshape Squares (at least 200). Then the lesson begins by everyone making a cube and unfolding it so that:
Note: If the students happen to not produce different nets, the teachers can unfold their one in a different way as a stimulus to look for others. It is also not necessary to be told before beginning the investigation that there are 11 nets. The mathematician who first investigated these didn't know that. However, if the investigation languishes, it is a fact that can be dropped in to revitalise the search.
