Exploring shapes

In Math we started to explore the shapes.We were wondering why should we learn about shapes? Students told me this.
``If you are an architect or engineer you need to know which shapes you can stack on top of each other and which you can not.``
``You need to draw the house plans.``
``If you want to build a dog house you need to know how to do it.``

Then we wondered where or when do you need the skills to recognize,sort, describe, compare and make connections?
``Every day in life.``
