   cookies. Blue Bear has 6 more cookies than Red Bear.”


3. The next player drops two bears on his number mat.
   The player announces the two numbers, states the
   difference, and tells a comparison subtraction story.

5. Players take turns dropping bears on their number
   mats, stating the difference, and telling the associated
   number stories.
