Dressing Mr. Cube
04/14/23 2
Challenge
Within the metaphoric situation ‘The Dressmaker’, pupils are asked to make a pattern for clothes for the Cube. To do this the following are available: a model of a cube, six squares of the same size as the faces of the cube, stickers, a big sheet of paper and pencils

Challenge
• The task was presented as a story: Mr. Cube has just arrived on Earth coming from the Cube Planet and he has no clothes.
• We have to find as many clothes patterns for him as possible.
• Each pattern will be made of six squares.
• We have to make sure he can put on the new clothes.

Challenge
• As a supplementary task: find the “zippers” of the clothes.
• The clothes should be coloured in an attractive way.
• Find the symmetrical patterns.• Are they all in pairs?• Have you found all the nets?
How many are there?

Comments
• The constructivist approach is obvious.
• The metaphoric language is clear, the clothes are the nets of a cube. Its role is to appeal to real life situations.
• The cube is not a building block anymore, but an “individual”.
• The real challenge is not to find a net, but all the possible ones.

Comments: strong points
• Some of the pupils had the idea of using first pins instead of stickers to connect the squares.
• They grasped the “zippers” idea very quickly.

Comments: strong points
• Some groups shared roles and therefore worked very quickly. They even expressed the cause of their efficiency: teamwork.
• They had the idea of having five fixed squares and a mobile one, in order to find more nets.
• They found the symmetrical nets (“brother and sister”).

Comments: weak points
• A funny one: after finding two symmetrical nets, they turned one of them upside down and said: we have triplets!

Conclusions
• It was a task the pupils particularly enjoyed, despite the time and effort they had to put into it.
• It took them into 3-dimensional space and had a “story” attached to it, these are two of the reasons it was so popular.

Follow-up
• Create at least one clothes pattern for Mr. Cube’s family: his parents, Mr. Cuboid and Mrs. Prism, his wife, Mrs. Sphere and their son, the young Cone.
• Is this always possible? Why? Which member of the family can only get one pattern and which one none?
