Collaborative Station bottles in 3 different ways.

  • We will be playing a ratio version of I Spy.

  • There will be a picture with many different objects in it.

  • Partner A picks two objects and says their ratio. “I spy two objects with a ratio of 2 to 1.”

  • Partner B (and C) try to guess what two objects Partner A was thinking of.

  • Once the objects are correctly guessed, write down the ratio on your work paper and have the next person pick two objects.
