First the students thought about how many LEGO pieces each picture had and worked to put them in order.
Then they counted and checked.
Then the arranged the information in order.
Remarkably their ordering only differed in two places and each
of those only differed by 4 pieces.
For some thinking.
Lateral thinking - an Edward DeBono example.
4 blocks. Touching is defined to be surface to surface - not edge or corner.
1. Each block touch exactly 2 others,
2. Each block touch three others.
They each touch all the others.
3. Each touch 1.
4.
1 touch 1
Another touch 2
Another touch 3
Question - What does the fourth block touch?
