Sky sceapers

We did problem solving today in grade 9.  Each of these skyscraper templates show the number of buildings that can be seen from that perspective.  Each row and column can have 4 buildings, one of each height (1,2,3,4 levels).  

We thought about our strategies…

Some groups placed all the tallest buildings first.

Others worked from one corner…

It takes a lot of verification to make sure that the puzzle is solved correctly.

We worked hard, and used our logic and reasoning.  We also used our teamwork and communicating!
