Instructional Ideas

  • Provide opportunities that require justifications using geometric properties
  • Create groups based upon the justifications of the parallelogram to see if groups can find other ways
Classroom Considerations

  • The class should be familiar with proving quadrilaterals are parallelograms
Pros

  • The rubric breaks down the point allocation for a correct answer and justifications
  • Teacher notes connect the performance on the task to van Hiele Levels of geometric understanding
Cons

  • None
