Examples of an error:

  • The wrong scale factor has been used but the box has been enlarged consistently using that scale factor.
  • One square of the net has sides that are not 4.5 units long.
  • One row of squares is consistently too wide or too narrow.
 All correct – difficult
 
1 error only – easy
