Students Will Enjoy Hunting for Parallel and Perpendicular Lines in 2D Shapes 

Enhance your students’ understanding of parallel and perpendicular lines in 2D shapes with this versatile sorting activity. This resource encourages hands-on learning as students sort 24 unique shape cards into categories based on the presence or lack of parallel and perpendicular lines. Perfect for reinforcing key geometric concepts, this resource includes sorting mats, recording sheets, and answer keys to support your teaching. Help your students master the identification of parallel and perpendicular lines in an interactive and fun way!

Here are the categories on each sorting mat in this parallel and perpendicular lines in 2D shapes sort:

Sorting Mat 1 Categories

  • Shapes with Parallel Lines but NO Perpendicular Lines
  • Shapes with Perpendicular Lines but NO Parallel Lines
  • Shapes with NEITHER Parallel NOR Perpendicular Lines
  • Shapes with Parallel AND Perpendicular Lines

Sorting Mat 2 Categories

  • Shapes with Exactly One Pair of Parallel Lines
  • Shapes with Two or More Pairs of Parallel Lines
  • Shapes with Exactly One Pair of Perpendicular Lines
  • Shapes with Two or More Pairs of Perpendicular Lines

Introduce Attributes With Parallel and Perpendicular Lines in Shapes

There are many different 2D shape attributes to teach, so using this parallel and perpendicular lines in shapes activity is a great place to start. Once students have mastered this concept, move on to other shape attributes, such as: 

  • Number of sides
  • Length of sides 
  • Number of angles 
  • Types of angles
  • Number of vertices
  • Curved vs straight lines
  • Lines of symmetry
  • Regular vs irregular 
  • Concave vs convex

We have provided a Google Slides editable version of this parallel and perpendicular lines in 2D shapes resource. Modify the sorting mats to make sorts that align with the attributes above to give this resource many more uses!
