Students know:
  • Different properties are suited for different purposes.
  • A great variety of objects can be built up from a small set of pieces.
  • Structures can be disassembled and rearranged into new and different structures.


Students are able to:
  • Disassemble a structure into small pieces.
  • Assemble a new structure using the same small pieces.
  • Provide a written and/or oral explanation that correlates with a demonstration detailing the characteristics of the new object or objects.


Students understand that:
  • Structures may be broken into smaller pieces and a new structure, that is different in size or shape, can be formed from the same pieces.
