Task administration: 
This task can be completed with pencil and paper or online (with auto-marking displayed to students).  
It has a practical component.
 
Equipment
Blu-tack; sticks or straws in the following quantities: 4 sticks each 12 cm; 8 sticks each 6 cm.
  • This task is for students to carry out individually.
  • This task is completed with pencil and paper, and other equipment.
  • Check the student's shape before they do part b) to make sure it is a rectangular prism.
  • Students may do part b) only from an existing skeleton model. If students use a prism built by someone else then no marks would be allocated for part a).
