Volume as Additive: Data for My Hamster Mansion Activity
  • Invite students to think about the space around them: their school, apartment or home. Someone designed those spaces.
  • To get students thinking as designers, in small groups or pairs, prompt them to list some of the issues that architects need to think about when they design a living or work space for people. What things do they need to consider? Possible ideas include: bathrooms, size of rooms, being able to move from one floor to the other, place to eat, etc.
  • Share out ideas, for fun.
