Whales Blow

I had my students working in centers a couple of days ago.  Hattie was working on a center of Main Idea and Supporting Details.  Her main idea was "Whales blow."  She did have supporting details to go with it though.  Some of those were: "Whales can be identified by the size of their blows." "Right Whales make 2 low blows with their twin blow wholes." "The sperm whale makes a blow that is angled forward." :)
