  • Activity:
    • Give students a shape sorter.
    • Ask them how they would know which shape goes in which hole.
      • Students typically understand that they do not put a square block in a round hole, but why?
      • What makes the round block unique from the square block.
      • What makes the blocks similar.
    • Help students understand how to find the commonality in objects for Class creation.
      • What makes the object unique such that you would need to add to the subclass.
