Play with angles

In Hans Perssons book "Experiments with mathematics" there are a task called Play with angles and we did that today. The mission is to build a path through all the mirrors so that the beam from a laser pen can get from start to finish. 
It was a fun task, and this group got all the way from start to finish.
One challenge was to design something that could hold the mirror straight up, otherwise the beam went up at the ceiling or down at the floor.
Linnea was very focused when she got on her thinking mustache:)
