Math Discussions

The students had a lot of math discussions in small groups today.  All the discussions pertained to polygons and especially quadrilaterals.  I heard some great math talk.  There was a lot of thinking going on throughout the classroom.  Below the pictures is one example of one problem they were asked to discuss in their groups.  Their answers are posted too.




What is the same in all the polygons?
What is different?
